Design and Control of a Multifunctional Grid-Connected Battery Energy Storage with Enhanced Performance Using SOGI
Abstract This paper presents the design and control of a multifunctional two-stage grid-connected battery to provide peak shaving along with reactive power and harmonics compensation. The system comprises of a bidirectional converter and a grid-connected voltage source converter (VSC). The bidirectional converter is controlled to provide the battery charging and to maintain constant DC-link voltage. A peak shaving logic is developed, and a ‘dual-mode synchronous reference frame control’ is designed using a moving average filter to control the VSC to provide peak shaving along with reactive power and harmonics compensation. A second-order generalized integrator is utilized to enhance system performance both during steady state and during mode transitions. The performance of the grid-connected battery system is tested for various scenarios in both simulation and experimentation. Simulated and test results validate the effectiveness of the proposed control in achieving the set objectives.
