Abstract: In this paper, a novel distributed unified controller is designed to solve the problems of unbalanced State of Charge (SoC), unreasonable load current sharing, and unstable DC bus voltage for parallel battery storage systems (BSSs) in DC shipboard microgrid (DC-SMG). Different from the droop-based secondary controller, the designed …
This marks a watershed moment in renewable energy projects in South Africa. The solar PV and lithium-ion battery system will form one of South Africa''s largest microgrids. The 1.8MW solar PV facility alongside a 2.9MWh battery is for use by a C&I customer. It is grid-connected and thus able to stabilise the local electricity grid.
