PSO Based Dispatch and Control of Hybrid Power System with PV-Diesel Generator- A Prototype

Abstract

A micro-grid is a small-scale power grid that can operate independently or in conjunction with the area's main electrical grid. Micro-grid paves way to power remote locations and effectively integrate various sources of distributed generation, including renewable. In this paper, an economical way of dispatching PV power and power generated by generators in islanded micro-grid is proposed. Here, part of the micro-grid demand is supplied by PV power station. The demand which cannot be supplied by the PV panel, are dispatched between DGs by solving unit commitment and economic dispatch problems. Unit commitment is carried out using priority list method and economic dispatch particle Swarm optimization. A hardware prototype for the proposed micro-grid dispatch methodology has been developed. Here, commitment and de?commitment of the sources and demands is carried out by generating control signals denoting the ON/OFF status to the sources for different intervals.
