Heat and power generation augmentation planning of isolated microgrid

Due to raising heat and power demand the microgrid has to be expanded to meet increased power and heat demand. A short-range heat and power generation augmentation planning (HPGAP) of an isolated microgrid incorporating plug-in electric vehicles (PEVs) is described and evaluated here. The objective of HPGAP is to find out the most cost-effective and reliable expansion plan for meeting the forecasted power demand and heat demand over a short-range horizon while fulfilling a large number of technical, reliability and social constraints. An archetypal test system with existing diesel generators, small hydro power plant (SHPP), solar PV plant, wind turbine generator (WTG), biomass-fuel-fired combined heat and power (BCHP) unit, battery energy storage system (BESS), plug-in electric vehicles (PEVs) and candidate solar PV plant, WTG, SHPP, BCHP units and PEVs is considered here. The problem is solved by using self-organizing hierarchical particle swarm optimizer with time-varying acceleration coefficients (HPSO-TVAC), fast convergence evolutionary programming (FCEP) and differential evolution (DE).
