Modeling, simulation and development of supervision control system for hybrid wind diesel system

Abstract

A simulation-based research work on developing supervision control system for hybrid wind diesel system (HWDS) is presented. Simulation models of HWDS based stand-alone system and micro-grid systems are developed with different types of generators for a fully-rated converter based wind energy conversion system (WECS). A multi-variable control system is developed and implemented into the simulation models of HWDS. An appropriate control system is developed for each generator chosen for the WECS in the HWDS. This control system optimizes the power generation and ensures power sharing between the two sources. A control system for load voltage regulation and power system frequency regulation is developed and implemented to maintain the power quality at optimum level. An improved maximum power point tracking control scheme is simulated to achieve maximum power generation from the available wind. Also a governor control system is simulated for the diesel generation system. In this work, HWDS based stand-alone system and micro-grid system is simulated to study the performance of the developed control system. The complete HWDS is modeled and simulated in a MATLAB Simulink environment. Simulation results to validate the performance of the developed control system are presented.
