Techno-economic scrutiny of HRES through GA and PSO technique

Abstract

Presented work analyses the feasible sizing of two different hybrid renewable energy systems (HRSE) are PV-wind-biomass hybrid systems and PV-Wind hybrid systems. The proposed system includes battery unit for storage purpose and diesel generator for reliable operation. The electricity price or cost of energy (COE) is minimised as objective function to decide the optimal solution of hybrid system using GA and PSO. The optimal size of HRES is selected based on the lowest value of COE. The optimal solution includes high reliability, maximum value of renewable fraction (RF), less emission and low penalty cost according to minimum COE. The maximum value of loss of power supply probability (LPSP) is assumed 2% in this case study for reliability analysis. This paper's aim is to present the techno-economic feasibility of above mentioned HRES for a remote area of Jamny Ven Village Barwani district, India. The optimisation results are evaluated through load following and cycle charging dispatch strategy furthermore the results are also compared using GA and PSO optimisation techniques. Hence, the main purpose of presented work is to compare the performance results of GA and PSO with minimisation of COE using load following and cycle charging dispatch strategy.
