Optimal sizing of PV/wind/battery hybrid renewable energy system considering demand side management

Abstract

This paper the effect of demand side management (DSM) on the sizing of hybrid PV/wind/battery energy in system has been considered. The pigeon inspired algorithm (PIO) has been used for optimization purpose and additionally an energy filter algorithm has been developed to minimize the fluctuations of power injected into the grid. The levelized cost of energy (LCE) has been taken as the objective function while maintaining the system reliability, healthy charge on the battery as well as the less fluctuations in the power injected into the grid. The simulation has been performed for both actual load and modified load after the DSM has been performed. To verify the results a case study has been considered and the simulations are carried out in MATLAB environment. The results indicate that the DSM considerably reduces the storage requirements and there by reducing the unit cost.
