This paper looks at a long distance heat transportation system based on an absorption process using a mixture of water and ammonia as a working fluid in order to use low grade heat available in the process industry. This paper aims at establishing the potential of using this method for economically transferring low grade heat from process industries to domestic heat sinks. To do so, the efficiency of transporting low grade heat sources identified in the process industries was examined. The economic distance was defined as the limit for economically transferring low grade heat from the source to the domestic heat sink. Based on a 10 year payback period, it was shown that heat could reach as far as 30-40 km for low grade heat sources at temperature as low as 80 °C. Finally, the economic distance was expressed as a function of the amount of fuel equivalent associated with low grade heat recovery savings and the economics of the transportation solution was discussed with regards to the expected changes of the heating and steel price over time. © 2012 Elsevier Ltd.

The paper will present a novel Soft Switching Flyback Topology which utilizes the energy contained in the parasitic resonant circuit formed by the capacitance across the primary power switch and magnetizing inductance to create soft commutation for the primary power switch. The energy contained in the parasitic resonant circuit creates ringing across the primary power switch during the dead time. This energy is typically dissipated or dampened during the dead time period. The ringing across the primary switch during the dead time period can disturb the control IC that drives the synchronous rectifier in the secondary leading to accidental turn on which impact the efficiency and the reliability of the converter. The proposed technology eliminates this ringing by "freezing" the energy contained in the parasitic resonant circuit and by using that energy to create soft switching condition for the primary switch. © VDE VERLAG GMBH.

Residential Solar PV is being deployed in Australia at increasing rates. The distribution grid wasn't designed to accommodate local generation so impacts are expected to happen and challenge the way the LV network is being run today. From the various identified effects, this paper explores Voltage control aspects in particular. A set of 5 different options to deploy and use customer-owned inverters for reactive power compensation are presented, ranging from pure stand-alone inverter control and management to DNSP centralized control scheme. All options come with challenges which are also highlighted in this paper. There are also additional opportunities that could be brought by some of the propositions discussed and contribute to a more efficient and resilient grid. The paper concludes with a brief layout of what regulatory, tariff and standard implications would be implicit by the options forwarded. © 2011 IEEE.

Energy Storage has always been an attractive proposition for utilities. In fact, having more flexibility in managing demand and supply of electricity can help to improve the operational stability and efficiency of the power system which is an objective of both electricity industry and governments. Energy Storage has the capability of being the mediator between demand and supply and its adoption would increase the flexibility of the electricity supply system. In particular, on the Low Voltage side, DNSPs could benefit from having distributed storage in particular points on the grid. Storage could take the form of new systems or use spent EV batteries with enough capability for grid-connected stationary applications. There are a range of different benefits that can be harvested by different actors in the electricity value chain, which makes the task of identifying the value proposition for Energy Storage in LV systems a rather complex one. The Energy Storage device can be owned and/or operated by one of the identified actors. Whichever ownership and control method is chosen, there are important challenges in the creation of market rules for appropriate valuation of the benefits from distributed storage. Suggestions for more research are given. © 2011 IEEE.

The paper will present two novel Soft Switching Half Bridge Topologies used in a 1KW DC-DC Converter, operating after a PFC and providing an isolated 12V at 83A. The two topologies are derived from a conventional Half Bridge topology and through different means are converted to "true" soft switching topology. A "true" soft switching topology combines zero current at turn off in the secondary through the synchronous rectifiers and zero voltage switching across the primary switchers. This is accomplished in the first topology without any additional hardware, just through sizing and intelligent control. In the second topology, we add two small current "injectors" aimed in shaping the current through the rectifier means and primary switchers just during the transitions. In combination to a novel magnetic structure and intelligent control, this converter efficiency crosses the 99% efficiency barrier. © 2014 IEEE.

Biomass fuelled trigeneration is the term given to the system which is the on-site generation of electricity, heat and cooling simultaneously, using biomass as the fuel source. As a form of the renewable energy sources biomass is not intermittent, location-dependent or very difficult to store. If grown sustainably, biomass can be considered to be CO2 neutral. Biomass, therefore, would be a promising option for the future to contribute both to the reduction of greenhouse gases and to the solution of replacing fossil fuels in power plants. For a wide range of commercial buildings, biomass trigeneration offers an economical solution of providing power, heat and cooling which is more environmentally friendly than conventional methods. This work focuses on the modelling, simulation and techno-economic analysis of small scale biomass trigeneration applications. The Organic Rankine Cycle (ORC) integrated with conventional combustion provides electricity for building use. The waste heat recovered from the ORC system and exhaust gases is used to supply hot water to space heating and excess heat is also used to drive an absorption cooling system. In order to use energy resources most efficiently, the proposed process is modelled and simulated using the ECLIPSE process simulation package. Based on the results achieved, the key technical and environmental issues have been examined. The study also investigates the impact of different biomass feedstock on the performance of trigeneration plant, biomass ash content ranges from 0.57 to 14.26% ash and a range of moisture content 10.6-33.51%. The calorific value across the biomass sources ranges between 16.56 and 17.97 MJ/kg daf. Finally, an economic evaluation of the system is performed along with sensitivity analyses such as capital investments, plant load factors and fuel costs. The results show that the maximum efficiencies and the best breakeven electricity selling price for the cases considered in this study are as follows: 11.1% and 221 £/MWh for power only, 85.0% and 87 £/MWh for combined heat and power and 71.7% and 103 £/kWh for trigeneration respectively. © 2012 Elsevier Ltd.
