Battery energy storage system to reduce voltage rise under high penetration of customer-scale photovoltaics

ABSTRACT

Unmanaged high penetration of customer-scale photovoltaic on the distribution network results in voltage rises along the network. However, the performance of the implemented battery energy storage system (BESS) to prevent voltage rise under that high penetration condition was unclear because the previous penetration models did not consider the intermittency and variability characteristics of the penetration due to their model simplifications. Therefore, this research proposes a BESS control scheme to mitigate impermissible voltage rises by considering the penetration characteristics of intermittency and variability. As a result, the proposed model outperformed the previous model by providing a more complete representation of the actual penetration issues, and thus the expected contribution of the BESS control scheme in reducing voltage rises could be provided.
