With ever-increasing penetration of non-dispatchable intermittent generation resources in electric grids all over the world, the system operators are facing more challenges to meet the system AGC requirements which aim to maintain the target grid frequency and scheduled tie flows. The utility scale energy storage applications have been often referred to as one of the potential solutions for improving the system frequency response, especially the speed of response. A new concept relating to the use of Dynamic Available AGC (DAA) of the Battery Energy Storage System (BESS) is proposed in this paper and applied in conjunction with the priority and proportional AGC signal distribution strategies. Additionally, this paper proposes an independent AGC control strategy based on Area Control Error (ACE) signal distribution to further enhance the impact of the fast response capability of the BESS. The same is accomplished by means of implementing an independent Proportional Integral (PI) controller without low-order filter typically associated with the ACE signal distribution. The AGC simulation results based on generation trip and normal load variance events, as tested on the El Salvador system model, indicate significant benefits to the system AGC performance when using the concept of the DAA for the BESS and the independent AGC control strategy. The AGC simulation results also indicate that the utilization of 10 MW/3.66 MWh BESS can replace about 36 MW conventional AGC units on the tested system model without compromising on the AGC performance of the system for day-to-day variations experienced in the system load. © 2014 IEEE.

With the increase in the utilization of intermittent renewables such as wind and solar PV, integration of these resources into the existing grids requires a means of leveling the output. Batteries have been targeted as one possible means of achieving this, requiring increases in cycle and calendar life to ensure greater than 15 years of service. Altairnano has been developing large format batteries for use in frequency regulation as well as renewables integration. We have demonstrated power density in excess of 4000 watts per kilogram, a cycle life on the order 25,000 at 100% depth of discharge and 8C charge/discharge rate. To further increase the operating temperature range of these cells Altairnano plans to reduce electrolyte decomposition reactions by altering the surface chemistry of the electrodes.

Altair Nanotechnologies is going out to sea with the Navy, partnering with the military org to develop battery backup systems on the megawatt scale. The $2.5 million contract is the second such partnership Altairnano has made with the Navy in the last year. Reno, Nev.-based Altairnano’s (ALTI) ceramic lithium-ion batteries, dubbed “Nanosafe,” are different from other nanotechnology-based lithium batteries, like A123’s, in that Altairnano has replaced the traditional materials with nano-structured ones that can offer 100 times more surface area and don’t lose their ability to charge. In other words: faster charging and longer battery life. In fact, Altairnano claim their batteries charge so fast that they can fully recharge your electric car in 10 minutes. They claim the battery will even outlast your car. Such long-lasting batteries could give ideas like Project Better Place’s battery-swapping infrastructure some trouble. Altairnano is working on a number of vehicular projects. Altairnano has agreements to put Nanosafe batteries in Phoenix Motorcars’ electric SUVs and trucks, British Lightning Car’s luxury sports car, ISE Corp.’s hybrid buses, and Alcoa’s AFL Automotive’s hybrid trucks. But for batteries backing up parts of the grid, the potential for Altairnano’s technology to smooth out the problem of intermittent power sources like solar and wind electricity generation is large. The batteries don’t have a great energy density but that doesn’t matter if you have plenty of space to plop down a huge battery array next to a remote wind farm. Altairnano just finished construction on a $1 million dollar deal with power company AES to provide two megawatts worth of battery storage , an Altairnano spokesperson also told us. Altairnano started off using nanotechnology to produce pigment for paint, but over the last decade, have moved their nanotechnology into batteries. Currently they are finding the company has been losing money as they get closer to putting more batteries on the road. They lost $16.7 million dollars in the first three quarters of last year while only bringing in $7.5 million in revenue. Altairnano’s Navy deal is also the second major military investment in large-scale battery technology this month. Earlier this month, ceramic battery maker EEStor signed an exclusive international rights agreement with aerospace giant Lockheed Martin for put EEStor’s electric energy storage units on the battlefield. Looks like the military-industrial complex is helping the cleantech venture world.

For Deeya Energy, good things come in threes. The Fremont, Calif.-based startup, which is working on energy storage technology for three applications — replacing diesel generators, stockpiling renewable energy, and stabilizing the electric grid — has just closed a third round of financing. The oversubscribed $30 million round brings Deeya’s total venture capital investment since its founding in 2004 to $53 million. New investor Technology Partners — which has also backed Abound Solar and Tesla Motors — led the round, and existing investors BlueRun Ventures, Draper Fisher Jurvetson and New Enterprise Associates also joined. At this point, the company says it plans to use the new investment to expand operations and ramp up production of its so-called L-cell technology. Deeya’s modular devices (pictured) are an example of flow battery tech — they use large tanks full of dissolved electrolytes to store power at utility scale. Large-scale energy storage is getting to be a crowded space these days. Fellow startups EEstor, Altairnano and A123Systems are all looking to connect high-capacity, fast-charging energy storage devices to the energy grid. To be sure, updating the electric grid to make better use of wind and solar resources (which can’t be called up on demand like a coal-fired power plant) remains a work in progress. But the idea is to store excess energy generated at night or during other periods of low demand, and then deploy that clean power when demand spikes instead of firing up polluting power plants.

Adding digital intelligence to the power grid is getting all the attention right now from Congress, investors and entrepreneurs, but a next-generation smart grid without energy storage is like a computer without a hard drive: severely limited. Energy stored throughout the grid can provide dispatchable power to address peak power needs, decreasing the use of expensive plants that utilities power up as a last resort when demand spikes, making the network less volatile. Energy storage will also be crucial for making the most of variable renewable energy sources (the sun shines and the wind blows only at certain times) once they’re connected to the grid. In the way that computers and the infrastructure of the Internet have built up around storage as a key component, so will the power grid eventually rely on energy storage technology as a pivotal piece. But until recently, energy storage has been largely ignored — overshadowed by clean power generation or information technology for the smart grid. Mohr Davidow Ventures partner Marianne Wu said at an energy storage conference at UC Berkeley last week that over the past few years it’s been very hard to find entrepreneurs with long careers and innovative ideas in grid-focused energy storage. The small number of battery startups in the U.S. have generally been focusing on the sexier market of electric and hybrid vehicles. All that seems to be changing, though, as more attention shifts to the importance of remaking the power grid. The stimulus package is allocating billions specifically for energy storage and advanced battery technology for the power grid, among other applications, in addition to the billions set aside for adding digital intelligence to the grid that will help incorporate these storage technologies. On Tuesday morning, GE announced that it’s building a battery factory in New York state in order to produce energy storage devices for the power grid (as well as heavy-haul trains) and is looking for stimulus funding. Private investors are also seeing the new opportunities: While venture capital investments for the first quarter of this year dropped across the board, energy storage technology for vehicles and the grid received $114 million, making it one of the only bright spots, according to Ernst & Young and Dow Jones. That was more than double the $50 million venture capitalists invested in the quarter a year prior. If funding news coming out of the current quarter is an indicator of things to come, the energy storage boom will continue. Last week grid energy storage company Deeya Energy announced it has nabbed $30 million. Battery companies that have been developing devices for vehicles are also increasingly eyeing applications for grid power. A123Systems, the lithium-ion darling backed by GE, installed its first Hybrid Ancillary Power Unit at a power plant owned by AES in Southern California last November. Around the same time lithium titanate battery maker Altairnano announced that it is supplying a 1 MW battery storage system for a major transmission region. And ultracapacitor company EEStor was reported to be in “serious talks” with potential solar and wind energy partners to help boost grid capacity by providing its devices for utility-scale electricity storage. But beyond advanced batteries and ultracapacitors there’s a variety of technologies being tested for the power grid. These nine are among the most promising: Compressed Air: Compressed air is a decades-old technology which takes excess energy from a power plant or renewable energy and uses it to run air compressors, which pump air into an underground cave or container where it’s stored under pressure. When the air is released, it powers a turbine, creating electricity. Utilities like PG&E are starting to investigate this technology because it is one of the lowest-cost and simplest energy storage technologies. But pumping compressed air underground has some environmental and safety concerns, so the process for getting regulators to approve these projects takes a long time. There’s only a handful of compressed air energy storage projects in the world, including one in Alabama and one in Germany. Entrepreneurial ventures in this space are rare, but a joint venture called Energy Storage and Power, which is a partnership between Public Service Enterprise Group, owner of New Jersey’s largest utility, and inventor Michael Nakhamkin, emerged last year. Pumped Hydro: Pumped hydro storage is the most widespread energy storage technology used in the world, according to the Energy Storage Association. There are about 90 GW of pumped storage in operation, which equals about 3 percent of worldwide generation capacity. The system works by pumping water from a lower reservoir to a higher reservoir and then letting the water move downhill to produce electricity when needed. Traditional iterations of the technology are ideal for populations that live close to high altitude terrain, like Switzerland, where pumped hydro has been used for a century. Ultracapacitors: A new generation of ultracapacitors is emerging, aiming to seize the future of the auto industry — can they revolutionize the power grid, too? Capacitors have traditionally been used to produce quick bursts of speed and to deliver fast charge times, rather than for endurance, but some of the newer ultracapacitors are getting better in this area. EEStor is one of the more well-known of the group and, as we’ve already pointed out, it has been reported to be talking to renewable energy providers. Graphene Energy, an Austin-based ultracapacitor developer that emerged in January and is seed funded by Quercus Trust, works with the strongest material ever tested — a one-atom thick sheet of graphite — and is looking to apply its device to the power grid. Flywheels: Flywheels are large discs that spin in a vacuum and are sometimes used as backup power for an uninterrupted power supply (UPS), which are emergency power systems that turn on after a power outage before a generator kicks in. Flywheels have the benefit of needing little upkeep over a 20-year-plus lifetime and don’t contain toxic chemicals the way some batteries do. The amount of power delivered to the grid depends on how fast the flywheel spins. But flywheels have faced some hurdles in reaching mainstream commercialization including technology development, difficulty finding the right market and competition with batteries. (For example, flywheel maker Beacon Power recently said it is delaying the expansion of a small commercial project that it had been planning to build out to 5 MW.) Sodium Sulfur (NAS) Batteries: Sodium Sulfur or “NAS” batteries use simple ingredients — liquid sulfur and salt — and have been used on Japan’s power grid for years. According to the Electric Storage Association, there are over 190 sites and 270 MW of stored energy from NAS batteries in Japan. In GE’s battery factory announcement this morning, GE CEO Jeffrey Immelt said GE will be building sodium-based batteries at its plant and said that the company has over 30 patents in the space. Flow Batteries: Similar to fuel cells, flow batteries are a decades-old technology that converts chemical energy into electricity. Oftentimes the electrolyte is stored in large external tanks, and the rate of how the power is stored and delivered can be managed. Another advantage of a flow battery is that it can be recharged quickly. The tech is older, but some entrepreneurs see newer opportunities, and Deeya Energy is an example of a new flow battery startup that recently received funding. Lithium-ion Batteries: Much of the advancement in batteries (for the grid and for electric vehicles) is being done with lithium-based batteries like the ones made by A123Systems and Altairnano. Compared with the incumbent technology, lead acid batteries, lithium allows for faster charging, lighter weight, and higher energy density and is poised to be the moneymaker of the world battery materials market in the coming years. Lead Acid Batteries: Lead acid batteries are the oldest, most mature form, of batteries for energy storage, and the technology is relatively cheap and widely available. But the chemistry has its barriers, including lower energy density and heavier weight. Some entrepreneurs are trying to breathe new life into lead acid battery technology, including Axion Power, a Quercus Trust-backed startup working to blend ultracapacitor tech with old-fashioned lead-acid batteries for a lead 2.0 device. Fuel Cells: Fuel cells produce electricity through an electrochemical conversion, and can be quickly recharged by updating a fuel cell device with a new solution. Fuel cells have long been thought of as the holy grail of energy storage technology — for consumer electronics, vehicles and the power grid — but have so far failed to make it to mainstream commercialization. They may fare better in the power grid market, since the need for rock bottom prices in the gadget and car markets has been one of their biggest barriers. Bloom Energy is a high-profile startup working on a large-scale fuel cell that could help stabilize the power grid and promises to have its device ready within a year or two.
