Comparative assessment of two different modes multi-objective optimal power management of micro-grid: grid-connected and stand-alone

摘要

This study presents a multi-objective problem of the optimal power management of micro-grids, which is based on modified Tribe-PSO. Minimising total cost and emission over a 24h time horizon are the objective functions in this problem. For the participation of consumers in the management of micro-grids, demand response program is used. The scheduling approach is tested on the IEEE standard distribution network with 33 buses and is compared in two modes: grid-connected and stand-alone. Simulation results show that the presented power and demand scheduling provide a lower operation cost and more efficient utilisation of the renewable energy sources and the demand response programs.
