The Impact of Different Control Strategies on Residential Battery Degradation

Residential batteries are attracting prosumers due to their ability in reducing the electricity bill by maximizing the solar PV self-consumption as well as optimizing the time of use tariff (ToUT). Furthermore, the deployment of residential batteries is increasing due to their potential in supporting the network from the operator’s point of view. The control of residential batteries can be categorized into real-time and look-ahead. The real-time control usually aims to achieve self-consumption maximization (SCM) by charging the battery using the excess PV generation. The SCM can be adjusted to optimize the ToUT by charging during low ToUT periods when the PV generation is insufficient. The look-ahead control utilizes the forecasting to schedule the battery using an optimization solver. This work investigates the impact of these three different control strategies on battery degradation for different capacities. Other comparisons for the electricity bill reduction and network losses are also considered.
