Dynamic Simulation Model of Microgrid Based on Photovoltaic for Power Quality Improvement

Abstract

A microgrid consists of cluster of loads and distributed generators that operate as a single controllable system. Power quality can be improved by proper load sharing between grid and integrated photovoltaic. Microgrid system used for renewable distributed generators and PV power generated can be stabilized according the load demand is presented in this paper. MATLAB/Simulink software is used to design the photovoltaic generation which is validated on IEEE 14-Bus network system. Power quality for furthest lines from main generation area will be improved by integrated PV to weakest buses in the network. As a result, power flow is improved and the power loses is reduce significantly. The performance of the PV injection is also compared with different power rating under different operating conditions. The test results revealed that the power quality at weak buses is significant improved and the load sharing between network grid is achieved with additional power injection.
