Control and Coordination of multiple BESS in a Low Voltage Distribution Network

MSc thesis of Margarita Kitso

Renewable energy sources are characterized by an intermittent and stochastic character which affects the
power production from renewable energy technologies and may pose challenges to the grid. BESS can
contribute in facing those challenges. In this thesis study, a coordination control strategy of multiple
BESS was developed to address the network’s voltage violation issues caused by the high penetration of PV
units. The coordination control strategy is based on a consensus algorithm that determines each BESS’s
contribution to the network so that voltage of buses is maintained within the limits.
