Abstract
Dilute and random nature of renewable energy resources forms the basis of hybridization. A hybrid renewable energy system serves its best when optimized with appropriate dispatch strategy. This paper presents the optimization of hybrid renewable energy system based on steady state energy balance simulation approach with a combined dispatch strategy that results in an optimum combination of components guaranteeing the minimum levelized cost of energy for a given maximum allowable annual capacity shortage. The proposed approach of optimization is written in the Java programming language that allows easy handling of the data and constraints and also supports multithreading. It implicitly determines the penetration of the resources based on the annualized life cycle cost of net energy contributed, hence there is no worry regarding the feasibility of a particular resource. Also, demand constraint considered for battery, genset and other components of the system aims at reduction of unnecessary energy generation and conversion thereby reducing the components’ size, O&M cost and human involvement and finally the cost of energy. A build-lease-transfer model of community bio-digester is also proposed which is found to drastically cut down the fuel cost and hence cost of energy along with the cost of waste management, finally benefiting the community.
