Abstract

The instability of the production of renewable energy resources (RESs) is a major problem for its installation and integration with the utility grid. A hybrid AC/DC microgrid facilitates the good operation of RESs with a storage system in grid-tied mode and the possibilities of smart energy management. The present work is being carried out on smart control strategy for a hybrid AC/DC microgrid (HMG). This paper deals with a real-time Hybrid control system (HCS) for a grid-connected HMG where the supervisory control based totally on fixing an optimization hassle objectives to minimize operating cost with the maximum usage of renewable resources, minimum usage of the utility grid, extending energy storage systems (ESS) lifetime. The power references for renewable energy resources (RESs) are scheduled by the use of CPLEX solver which uses as input strength measurement, archived facts and stored climate forecast statistics previously measured regarding the modern status. The experimental study verifies well the supervision methodology; thus, the proposed algorithm respects the optimization in real-time operation under different constraints.

Summary

Introduction

The intellectual concept can be achieved in microgrids (MGs) [1]. The RESs are mainly used as microgeneration in the microgrid to cover the power demands of buildings and even small population areas. A microgrid consisting of the two sub-grids (AC and DC grid) allows AC network elements such as AC generation and loads and DC network elements, such as batteries, fuel cells, PV arrays, wind and DC loads, etc. The transfer of power between DC and AC links lead to the good functioning of the power system below different conditions of generations and loads [2] [3]. The DC and AC buses are linked by bidirectional interlink converter wish transfers power. The role of the battery is very important for temporal shifting of energy and for reliability purposes. The battery allows energy imports from the grid and renewable sources (PV arrays and wind) to be stored to be used at opportune times. The role of Revised Manuscript Received on March 17, 2020
