Cycle-charging dispatch strategy based performance analysis for standalone PV system with DG & BESS

The goal of this paper is analyzing the performance of a standalone PV with battery energy storage system (BESS) and diesel generator (DG) as a backup available in a rural area of Khurda district in Odisha, India considering the average hourly solar irradiation, ambient temperature and load profile of that location which will help the small remote village avail electricity. In this paper the dynamic models of hybrid system as well as cycle charging dispatch control strategy are considered. The timed performances of the battery energy storage system with a standalone solar PV and diesel generator system is determined so that the hybrid system will be sufficient to feed the load demand and decrease the overall maintenance cost of the system by reducing the cost of fuel for the diesel generator. Moreover such models can be used in the assessment, sizing, control and performance evaluation of hybrid solar PV, diesel generator and battery storage system.
