    Transient behavioural modelling of Battery Energy Storage System supporting Microgrid
    (Institute of Electrical and Electronics Engineers Inc., 2020) Joshua, A.M.; Vittal, K.P.
    Energy storage is a vital component for a resilient microgrid. The high investment cost associated with storage is the major deterrent for its integration in a microgrid. But with the advent of Electric Vehicles and Smart Grids, battery technology and its mass production have got a huge thrust. Cost of the battery is anticipated to come down in future and battery storage customary in microgrids. Though storage will solve all problems related to power mismatches between generation and loads, it brings some additional challenges. Due to the bidirectional power flows, control and protection become complicated. For an effective microgrid protection design, there is a need to study the transient behaviour of its components. In this paper, a microgrid model with a centralised Battery Energy Storage System (BESS) is built. The control strategies automatically switch between grid connected and standalone modes of operation. The model is verified using PSCAD simulations for various operating scenarios. This paper emphasises the role of BESS in a microgrid and investigates the transient behaviour of Distributed Generators (DGs) under various faults in grid connected and islanded operation modes. © 2020 IEEE.

    Adaptive Protection of Solar PV Microgrid Without ESS
    (Springer Science and Business Media Deutschland GmbH, 2024) Meitei, L.P.; Vittal, K.P.; Pinto, J.A.
    Conventional sources play a major role in today’s power scenario. However, the trend has now been shifted toward non-conventional sources, viz., Solar, wind, tidal, etc. considering the depletion rate of fossil fuels, transmission losses and environmental impacts. As a result, Microgrids are getting popular nowadays due to its high reliability, nature of operation, and low operational cost. In this paper, an adaptive protection scheme is developed in MATLAB for a solar PV Microgrid without Energy Storage Systems (ESS) which can operate in both Grid connected mode (GCM) and Islanded Mode (IM). © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd 2024.
