Design and Simulation of an Islanded Hybrid Microgrid for Remote Off-Grid Communities

To fulfill the Sustainable Development Goal of energy access (SDG 7), renewable energy sources are the main contributing force. This paper focuses on the electrification of remote islanded community with renewable energy sources. This paper proposes two electrification schemes. In first scheme, the whole village is centrally electrified with the use of biodiesel generator, solar PV and with battery banks as storage. With the addition of renewable energy resources in the grid due to its intermittent nature causes fluctuations in frequency. The paper shows the design of frequency controller incorporated with battery to reduce frequency fluctuations. To investigate, a microgrid comprises of diesel generator, solar P.V as generating units with an external battery energy storage system as an ancillary service source to provide primary frequency response is modeled in MATLAB Simulink. In second scheme, a single phase decentralized design is proposed to electrify individual houses with solar and battery arrangement. To assess the effectiveness of the intended system, actual solar irradiance data and load profile of Pahadi village, Morena in Madhya Pradesh, India is taken into consideration.
