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 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.

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.}, keywords = {Energy management; Renewable energy resources; Renewable energy source; Renewable energy sources; Electricity; Pinch analysis; Load shifting; Hybrid power systems; Process change; Process changes; Power Pinch Analysis (PoPA)}, year = {2013}, eissn = {1618-9558}, pages = {459-472} } @article{MTMT:2199081, title = {A process integration targeting method for hybrid power systems}, url = {https://m2.mtmt.hu/api/publication/2199081}, author = {Wan, Alwi SR and Mohammad, Rozali NE and Abdul-Manan, Z and Klemeš, Jiri Jaromir}, doi = {10.1016/j.energy.2012.01.005}, journal-iso = {ENERGY}, journal = {ENERGY}, volume = {44}, unique-id = {2199081}, issn = {0360-5442}, abstract = {Pinch Analysis is a well-established methodology of Process Integration for designing optimal networks for recovery and conservation of resources such as heat, mass, water, carbon, gas, properties and solid materials for more than four decades.
