Fuzzy Logic Controller Design for Voltage, Frequency, Current and Power Control of Three-phase Distributed Generation Based Islanded Microgrid

Abstract

Today's clean technologies related to microgrids are approaching towards the smart nanogrid system. It fulfils the demand of the electricity throughout the world by proper using of renewable energy sources and energy storage systems. Still, the microgrid (MG) power plant control has enriched to a level that it will require complicated and smooth control in the grid interaction including distributed islanding operation. The load dynamics and uncertainties are the common issues which hampers the frequency, voltage and power profile of the MG that is responsible to damage the load and power system. The design of robust fuzzy logic controller (FLC) has been proposed in this research article to regulate the performances of three-phase islanded MG. The performance of the proposed FLC has been examined under different loading condition whose robustness has been evaluated under faulty condition. The investigated performances of the MG ensure high tracking and robust performance of the proposed FLC.

Microgrid to smart grid's evolution: Technical challenges, current solutions, and future scopes

“…Based on the power control, these loads are characterized into two types such as critical and noncritical load. 26,44,45 (i) Critical load: The critical load is defined as a load that requires high quality and reliable power to operate. The loads used in the hospital, military base, fire station, water infrastructure, or communication sector are usually critical loads that need to be controlled efficiently and regularly without breaking down the connection for human safety.…”
