Optimal Dispatch of a Hybrid Renewable Energy System Using Modified PSO Algorithm

Hybrid power system is expected to be major part of next electricity revolution for supplying power to remote areas where the grid power supply is almost impossible in term of cost and geographical location. Distributed hybrid renewable energy power system could afford power supply to these areas under grid and off grid connections. Here in this paper attention has given to minimize the price of generation system integrating the renewable energy sources with the existing power supply system. A solar PV, wind hybrid system with thermal power generation has been considered for economical dispatch of power. A modified Particle swarm optimization (MPSO) method has been applied to minimize the cost of power generation. This algorithm proves highly efficient for the dispatch problems. The main intention of this paper is not only to reduce the price but also the best use of renewable sources locally available, so that the carbon emission and global warming can be controlled.
