Efficiency Improvement of a Hybrid Power System using Lead-Lag Compensator (LLC)

Abstract

Installation of hybrid electrical power system is imperative to fulfil the escalated energy demand of consumers. Now a days, there is a propensity in using renewable energy resources due to its cost effectiveness. However, multiple generating systems and the switching between them creates serious problems regarding distortions and harmonics which needs to be eliminated. In this study, a grid connected hybrid system has been proposed with linear loads. The hybrid system works under the standard conditions of wind and temperature. System has been assessed by applying Newton Raphson method and efficiency has been improved by using lead lag compensator (LLC). ETAP software has been used for simulation purpose. The effectiveness of the electrical system is measured by considering the load intake and consumption.
