Abstract
Distributed energy resources have enormouspotential and can meet the present world energy demand. Theaim of this paper is minimization of net present cost ofmicrogrid which involves investments, replacement, andoperation and maintenance over its 20 years of operation.Prices are all empirical and components are commerciallyavailable. The microgrid considered in this paper consists ofwind turbine (WT), photovoltaic array (PV), micro turbine(MT) and battery storage. A Particle Swarm Optimizationalgorithm is used to solve the optimization problem. Systemplanning based on stipulated reliability criteria leads to robustarchitectures which can meet the consumers’ requirements.This paper presents a method for determining sizing ofresources from the available types of DER. Reliability is ameasure of the system’s capability to serve the demand. Thereare various indices which quantify the reliability of a micro gridsystem. Since the wind is unstable and variable energy source,and behave far differently than conventional sources, in thispaper, we consider that effect as uncertainty on optimal size ofWT. At last, a simulation result shows the effectiveness of thesuggested microgrid.
