Real-time Performance Validation of a NSC based Microgrid during Grid disconnection
This paper presents a grid-connected hybrid microgrid system with improved power quality and an uninterruptible power supply. The proposed microgrid integrates a photovoltaic (PV) system equipped with battery energy storage (BES) with the conventional grid. These power sources are integrated using a nine-switch converter (NSC). Though NSC comprises two 3-phase AC terminals, one set of three-phase terminals is connected to the utility grid and the load is connected to the other set of three-phase terminals of NSC. Two different control algorithms are designed, namely load side voltage control algorithm which helps in keeping the load voltage at a constant value irrespective of source variation or disconnection. And on the other hand, the PQ control algorithm is designed to control both the real and reactive power at a constant value irrespective of any disturbance. The proposed work mainly focuses on source disconnection, and power management during source or grid disconnection. The proposed microgrid is implemented in real-time using the OPAL-RT platform and the results are verified.
