A Technical Analysis of a Grid-Connected Hybrid Renewable Energy System under Meteorological Constraints for a Timely Energy Management

Abstract

Electricity demand can be met in a variety of ways, and the integration of renewable energy sources can be a reliable, environmentally sustainable, and cost-effective option. Energy needs in remote and isolated areas not served directly by the electrical grid are best met by hybrid systems employing many renewable energy sources. This is especially true in developing countries. Consequently, one of the greatest difficulties for developing nations is the establishment of grid-connected Hybrid Renewable Energy Systems (HRES). This is dependent on the findings of the feasibility study and, more importantly, the improvement of the constructed system. The purpose of this study is to lay forth a reliable structure for EMS-based tactics. PV/Battery/Grid-Tied Loads are the main components. As a result of the solar panels being shaded, the resulting Hybrid Micro Grid System (HMGS) is vulnerable to environmental factors such as wind and rain. In this study, we employ a heuristic method based on State Machine Logic (the State Flow Method), as well as a more traditional technique, Linear Programming. MATLAB R2018a was used to put these techniques into action. Both sets of simulation results—under clear and cloudy conditions—are compared and contrasted in detail. In light of the aforementioned parameters, four possibilities are provided. Every day, a unique case study undergoes a real-time analysis.
