The enhanced graphical tool employs new ways of utilising the recently introduced demand composite curve and supply composite curve while honouring and adapting fundamental energy systems engineering concepts. The SAHPPA method is capable of optimising the capacity of both the power generators and energy storage for biomass (i.e. non-intermittent) and solar photovoltaic (i.e. intermittent) energy technologies, which is a contribution to the emerging area of power pinch analysis. In addition, the procedure considers all possible efficiency losses in the overall system encompassing the charging-discharging and current inversion processes. © 2013 Springer-Verlag Berlin Heidelberg.

An optimal sizing method is the key factor to achieve the technical and economical feasibility of the HPS. Power Pinch Analysis (PoPA) method has been applied to set the guidelines for proper HPS sizing. Different scenarios for RE generators allow the designers to choose the best alternative for their systems. The scenarios considered are the reduction of (1) the size of the most expensive RE generator, (2) the size of generator with the most abundant RE sources available during the time interval with large electricity surplus and (3) the size of both the most expensive and abundant RE sources available during the time interval with large electricity surplus. The results show that the first option yields the minimum capital and operating costs and results in the lowest payback period for a given set of electricity targets. © 2013 Elsevier Ltd.

This appears to be one enhanced channel to tackle MSW disposal problem. WTE concept is incorporated into the MSW management system in this work. The integrated system is modelled to study its practicability and significance. The proposed model is illustrated with a case study involving the supply network design and the utilisation of MSW from urban sources. The modelling steps involve the generation of a superstructure, mathematical model construction, optimisation and solution interpretation. The MSW availability and its utilisation are investigated through its supply network design. Optimal locations of processing hubs and facilities are determined. Following this, boundaries and sizes of the processing hubs are calculated. The benefits of WTE strategy from MSW is analysed and its energy generation potential is demonstrated. This WTE strategy acts as one potential MSW management scheme for all interested parties. © 2014 Elsevier Ltd. All rights reserved.

The graphical PoPA tools have recently been proposed to determine targets for the minimum amount of outsourced electricity and the maximum amount of excess electricity to be stored and reused in the hybrid power systems. The numerical techniques for PoPA have so far not been developed. This work introduces two new PoPA numerical tools known as the Power Cascade Analysis (PoCA) and the Storage Cascade Table (SCT). The tools can be used to determine (1) the minimum target for outsourced electricity, (2) the amount of excess electricity for storage during start up and normal operations, (3) the amount of transferrable power, (4) the maximum storage (e.g. battery) capacity for the off-grid systems, (5) the amount of electricity transferrable to the grid, (6) the amount of outsourced electricity needed at each time interval and (7) the time interval where the maximum power demand occurs. While the graphical techniques provide useful visualisation insights, the numerical tools enable more rapid and precise allocation of power as well as the determination of electricity targets. © 2013 Elsevier Ltd.

Different storage systems incur different types and amount of losses depending on the power conditioning as well as storage system efficiencies. This work focuses on the design of HPS with pumped hydro storage systems using Power Pinch Analysis (PoPA). The previously developed modified Storage Cascade Table (SCT) for HPS with battery storage is adapted to calculate losses associated with the pumped hydro storage system. The demonstration of the method on an Illustrative Case Study shows that the application of pumped hydro storage in HPS yield lower total losses in the system. The maximum power demand target is reduced while the targeted maximum storage capacity is increased compared to when battery storage is applied. © 2013, AIDIC Servizi S.r.l.

The Power Pinch Analysis concept has been recently implemented for the optimal design of a HPS. This work introduces a new graphical tool known as the 'outsourced and storage electricity curves' (OSEC) to visualise the required minimum outsourced electricity and the current storage capacity at each time interval during HPS startup and continuous operation. Heuristics for load shifting for the integrated HPS system that can lead to further reductions of the maximum storage capacity and the maximum power demand (MPD) have also been introduced in this work. Note that the routine load shifting strategies in energy management cannot be used without the knowledge on how the integrated HPS components interact with one another. Application of the new approach on case studies demonstrates that the OSEC can provide vital insights for designers to perform the correct load shifting. The results show that up to 50 % reduction in the maximum storage capacity and the MPD is achieved. © 2013 Springer-Verlag Berlin Heidelberg.

However its application to power systems analysis still needs development. This paper extends the Pinch Analysis concept used in Process Integration to determine the minimum electricity targets for systems comprising hybrid renewable energy sources. PoPA (Power Pinch Analysis) tools described in this paper include graphical techniques to determine the minimum target for outsourced electricity and the amount of excess electricity for storage during start up and normal operations. The PoPA tools can be used by energy managers, electrical and power engineers and decision makers involved in the design of hybrid power systems. © 2012 Elsevier Ltd.

AB - Energy use continues to rise and with it the emissions of CO2. Energy efficiency methods have been applied across sectors. Efficiency gains and energy use per manufactured unit have fallen, particularly in relation to the processing industry. Residential, work place, leisure, and service sectors still use large amounts of energy and produce large emissions of CO2 despite efficiency gains. Successful strategies used in the processing industry for integrating energy systems, namely Total Site targeting, have been applied to locally integrated energy sectors. The method shows that it can be successfully applied to integrate renewables into the energy source mix and consequently reduce the carbon footprint of these locally integrated energy sectors. © 2008 Elsevier Ltd.
