Study of hybrid energy system based on wind-diesel engine system

Satapathy, S (2014) Study of hybrid energy system based on wind-diesel engine system. BTech thesis.



The aggravated increase in energy demand has posed a serious problem for the power system’s stability and reliability, and hence has become of major concern. The shortcomings of conventional source of energy have paved way for renewable energy sources. The latter can form a part of a stand-alone system or grid connected system. A single renewable source of energy when integrated with other sources of energy it is termed as hybrid system. This thesis deals with wind-diesel engine system. Wind diesel hybrid systems (WDHS) obtain maximum contribution from wind and rest by diesel generators. They are handy for rural or island areas. In this thesis an active power control strategy has been developed such that when the wind alone is not able to meet the energy demand, without compromising the frequency a transition occurs to wind diesel mode so that the energy demand is met. Then the system’s dynamic performance is compared for two cases with squirrel cage induction generator and permanent magnet induction generator. The mathematical model considered uses a STATCOM to meet the reactive power need upon sudden step change in power. The performance and the analysis is done in a user friendly MATLAB/Simulink environment.
