Simulation Based Approach for Determining the Battery Control Strategy of a PV and Battery Pilot System

Abstract

Implementing sophisticated battery control algorithms by overriding the inverter’s built-in battery controls may introduce technical bottlenecks and additional costs. Such an approach is therefore rarely justified for small scale, behind-the-meter storage. This paper focuses on determining the parameters of an inverter-enabled, rule-based control strategy so that the battery is governed similarly to when an optimization-based strategy is used. A five-step procedure has been proposed for the determination of the operational parameters. High resolution measurements of the electricity consumption and PV generation of a pilot case are used to simulate system’s operation. Results of the simulations for days with high and low solar insolation are presented.
