CHP-Based Economic Emission Dispatch of Microgrid Using Harris Hawks Optimization

In this paper, the economically self-sufficient microgrid is planned to provide electric power and heat demand. The combined power-based needs strategic placement of distributed generators concerning optimal size, location, type. As fossil fuel cost emission depend mainly on types generator units used in microgrid, economic dispatch performed for an hour with a static load demand multiple demands over 24 h day. TOPSIS ranking approach as tool obtain best compromise solution. Harris Hawks Optimization (HHO) solve problem. For validation, obtained results terms cost, emission, are compared reported by DE PSO, which shows superiority HHO them. impact renewable integration also investigated. With energy integration, reduced 18% 3.4% analysis under demand, whereas h, 14.95% 5.58%.
