The bungalows of Oxspring may look an unlikely testing ground for a new technology billed as a way to help renewable power, stymie energy price rises and aid the local power grid. But later this month, dozens of homes in this South Yorkshire village will have a home battery installed as part of a £250,000 trial to see if they can make solar power more valuable to homeowners and less painful for grid managers. Smaller than the high-profile Powerwalls introduced to the UK by Elon Musk’s Tesla last year, the British-engineered batteries will be fitted for free in 30 homes with solar panels on their roofs and 10 without. The project is a response to what until recently would have seemed an improbable challenge for the UK: too much solar power. There are now 875,000 homes with solar photovoltaic panels, and that is beginning to pose issues for network operators. In Oxspring, a community energy company found it could only install solar panels at two in three homes because of constraints on the amount of power that can be pushed into the grid. Energy storage company Moixa and the local network operator, Northern Powergrid, hope their pilot will “timeshift” solar for use at peak times and show storage can reduce network bottlenecks and cut out the need for costly upgrades, which would be passed on to energy bill-payers. “In northern Europe, solar produces the most energy when you don’t need it [at midday]. The amount of solar in the UK is meaningful now, and that’s translating to challenges [to grids] and costs to customers,” said Simon Daniel, chief executive of Moixa, who sees better storage as the solution. The company has around 600 batteries in homes across the UK, which it aggregates to act like one big battery, effectively a virtual power station. The Oxspring householders will either benefit from using more of their solar power – the electricity is more valuable if consumed in the house rather than exported to the grid – while the non-solar homes will get a cheque of £50-£75 each year from Moixa for aiding the local network. The trial near Barnsley is just one sign of a growing energy storage market in Britain. Companies such as Tesla and London-based Powervault do not publish sales numbers, but Germany’s Sonnen says it has sold hundreds of storage systems in the UK. The total installed is thought to be in the four figures. Most players have so far targeted householders hoping to increase the financial gain from their solar panels. But the introduction of time-of-day energy tariffs, enabled by smart meters, mean householders could potentially store electricity when it’s cheap, for use later when it’s pricier. Combined with the advent of rebates for “grid services” to connected batteries such as the Oxspring ones, they could dramatically widen home batteries’ appeal. Industry group the Electricity Storage Network describes 2017 as a “watershed” year for the technology. Sonnen said it was receiving a surge of customer enquiries, and predicted the UK market would take off this year. Powervault, which says it wants to make home batteries as commonplace as dishwashers and washing machines, started a £625,000 trial in south-east England last month. The project with UK Power Networks involves batteries in 60 homes. “The purpose is to enable us to harness more of the solar energy that’s generated during the day, when demand for energy is low, and release it onto the network at the morning and evening peaks,” said a spokesman for UK Power Networks, the UK’s biggest network operator. “National Grid spends about £1bn a year balancing demand and supply of energy. Currently they pay that money largely to big power stations but in the future we’ll move to a scenario where it also goes to a collective of batteries,” said Joe Warren, MD of Powervault, which began selling home batteries in 2014. He said Tesla’s arrival last year raised consumer awareness and argued that the market is big enough to sustain several companies: “There’s definitely room for a British energy storage player.” However, its US rival is upping the ante with a new, higher capacity version of its battery, which is in such demand that anyone buying one today can only get it in March at the earliest. Tesla, which earlier this month switched on the first sections of its battery-making Gigafactory in Nevada, begins installing the first of the new generation of Powerwall 2s in UK homes in February.

The significant decline of reactive power (Q) demand in the UK is considered one of the factors that led in 2011 to over-voltages in the 400kV network. To examine this, a distribution network known to have this decline is modelled in detail (from the transmission interface, 132kV, to 33kV) and validated using monitoring data. In particular, the effects from replacing overhead lines with cables as well as P and Q demand trends (at primary substations) on Q exchanges at the GSP are investigated. Results for this particular distribution network show that high cable penetrations in 132kV circuits lead, during minimum demand, to Q gains many times larger than its 2013 level. In addition, the identified P and Q demand trends at primary substations highlight the future larger Q injections through the transmission interface. These findings can be used to coordinate operational and planning actions between networks operators. © 2015 IEEE.

The present paper describes a methodology for evaluating major system risk on distribution networks, developed for and used by a distribution network operator (DNO) located in the North of England. Its purpose is to assess and rank each primary load point across the network as regards both the probability of extreme events occurring, and their consequence, expressed as a single major system risk index (MSR). This methodology was applied to around 150 separate load points, and the 40 with the highest MSR were further investigated to identify a range of possible mitigation strategies in each case. The paper concludes by evaluating the benefits of such a methodology to support long term network planning across a whole DNO, and by suggesting ways in which its applicability could be extended.

Installed capacities of distributed generation (DG) are projected to increase substantially in Great Britain and many other power systems. This paper will discuss the definition of capacity value of DG arising from its ability to support additional demand without the need for new network capacity, in analogy with the definition of effective load carrying capability (ELCC) at transmission level. This calculated ELCC depends on the precise detail of its definition; in particular in a demand group fed by a pair of circuits where the double outage state dominates the calculated reliability index, the ELCC will be very small unless the generator can run in islanded mode. Finally, requirements for use in practical planning studies and development of formal planning standards will be discussed. © 1969-2012 IEEE.

Wind Energy | Year: 2015
The reliability of power supply to distribution network customers can be increased by embedded generation, including wind farms. The value of this increase in reliability needs to be evaluated, and national standards such as the Great Britain security of supply standard P2/6 seek to do so. This paper appraises the capacity credit evaluation methodology in P2/6 and outlines an alternative methodology to integrate generation with load more effectively, taking into account the topology, loading and reliability of the surrounding network. It concludes that under certain circumstances, the presence of embedded wind generation can allow the deferral of costly network reinforcement projects but that the time for which reinforcement can reasonably be deferred is a function not only of the generators themselves but also of the surrounding network.

Through example, this paper discusses how a clear "Line of Sight" has been established throughout an asset management process for overhead line steel towers. Several condition assessment methods are presented, each with an emphasis on collecting consistent, accurate condition information suitable to gain maximum benefit from Condition Based Risk Management, itself a process which allows companies to use current asset information to justify and optimise future intervention expenditure. The example presented here demonstrates how the processes have been integrated within Northern Powergrid, a major UK Distribution Network Operator, as key components within their adopted inspection and refurbishment strategy for overhead lines.

The UK government's CO2 emissions targets will require electrification of much of the country's infrastructure with low carbon technologies such as photovoltaic panels, electric vehicles and heat pumps. The large scale proliferation of these technologies will necessitate major changes to the planning and operation of distribution networks. Distribution network operators are trialling electrical energy storage (EES) across their networks to increase their understanding of the contribution that it can make to enable the expected paradigm shift in generation and consumption of electricity.In order to evaluate a range of applications for EES, including voltage control and power flow management, installations have taken place at various distribution network locations and voltage levels. This article reports on trial design approaches and their application to a UK trial of an EES system to ensure broad applicability of the results. Results from these trials of an EES system, low carbon technologies and trial distribution networks are used to develop validated power system models. These models are used to evaluate, using a formalised methodology, the impact that EES could have on the design and operation of future distribution networks. © 2014 Elsevier Ltd.

This paper draws on several years of experience of developing condition based risk models at Northern Powergrid, examining how actual experience has influenced further model development in particular with regard to forecasting techniques and the updating of model parameters. Of special interest are the following aspects of our experience: degradation forecast error; unforeseen effects on asset condition; parameter uncertainty. We conclude that, models developed at Northern Powergrid provide useful investment decision support in the production of robust business plans as long as the model limitations are fully understood and managed.
