A Qualitative Analysis of an Intelligent Use of Demand and Generation in the Microgrid

Abstract

There are reliable solutions for overcoming the mismanagements and inefficiencies in the microgrid, which have been discussed, in the following proposed study. It focuses on the utilization of Renewable Energy Sources (RES) for operating the microgrid in a smart way such that the supply demand ratio is balanced profiting both the utility user and the end user. Power sources are scheduled as per requirement based on their availability and per unit cost. Centralized Multi Agent System (MAS) technique is adopted in which a central controller controls the operation of the whole microgrid system. Load agents attached to the system are of two types, i.e., critical load and non-critical load. The power to the critical load is to be maintained as a result of which in case of any emergency situation the power supplied to the non-critical load is shed off in order to make the critical load running. Different techniques are utilized for load management. Demand Side Management (DSM) is one of those techniques in which the load shifts from peak to off-peak hours and vice versa. Further, on the simulation of the proposed study has been performed in MATLAB/Simulink software and its hardware implementation has been done as well. The output results achieved indicates the supply to the load agents depending upon the availability of the power sources.

Decentralized Smart Energy Management in Hybrid Microgrids: Evaluating Operational Modes, Resources Optimization, and Environmental Impacts

“…Kofinas et al [15] proposed a Fuzzy Q-Learning energy management control strategy to ensure real-time control and monitoring of microgrid operations. Salam et al [16] proposed a microgrid model based on centralized MAS control by dividing the load into critical and non-critical loads. The RES is scheduled by utilizing the Demand Side Management (DSM) technique such that the non-critical load sheds its power to support the critical load in case of low power supply to the critical load.…”
