Abstract:

In order to improve the comprehensive benefit,including the reliability and the economy,of the standalone distributed generation system ( DGS) using hybrid renewable energy,an optimal design scheme based on the combination of wind,PV ( photovoltaic) and biogas resources is proposed. In the investigation,the characteristics of the three above-mentioned renewable energy resources,the main comprehensive efficiency index and the operational conditions of the generation system are all analyzed,and the structure of the DGS is designed. Moreover,the power mo-dels of the three kinds of energy resources,3 types of optimization objective models and the global optimization model of the system are established,and a coordinated control strategy of the generation system is finally presented. Simulation results show that the proposed optimal design scheme is effective and can acquire great comprehensive benefit for meeting the demand of dynamic load.

Key words: distributed generation system, hybrid renewable energy, global optimization, coordinated control strategy
