Multiobjective Optimization for Demand Response Services from a Battery Storage System

Abstract

This research analyzes an energy management system installed at an industrial production plant that coordinates a battery storage system in combination with a photovoltaic system for the day-ahead operation. The research quantifies the effect of single objective compared to multiobjective optimization for this photovoltaic-battery storage system using the lexicographic method and real electrical price and electrical demand data from a pilot site installation. The optimization results show a benefit in several metrics for combining multiple grid services using the lexicographic method, but prove the significance of the ranking of the multiple objectives. This ranking has to be done by the decision maker.
