Evaluation of a hybrid power system based on renewable and energy storage for reliable rural electrification

Abstract

Microgrids system consisting of single or multiple energy resources and storage is used to provide electricity to remote rural areas. Subsequently, they can be worked in both grid-connected and islanded modes. Microgrids can provide stable energy solutions to areas where grid extension is either costly or not feasible. The system's long-term economic stability and sustainability must be considered throughout the microgrid's design. Renewable energy sources have a variety of objectives and possible restrictions. The current plan suggests a rural microgrid with integrated solar, diesel, and battery systems. The proposed microgrid for the rural area of Uttarakhand (India) is given a techno-economic and feasibility analysis. For the hilly region of India, a standalone microgrid is created to handle the home peak load of 13kW. Moth flam optimization (MFO) is utilized to optimize the proposed energy framework, and the results are compared with those of a genetic algorithm (GA) and particle swarm optimization (PSO). The optimal hybrid system's net current and energy costs are calculated to be $58372.00, with the cost of energy per unit being $0.14/kWh. Sensitivity analysis and robustness viability have been performed for the configuration. The finding suggested that the energy framework using MFO is 18% and 16% less expensive than GA and PSO, respectively. This research adds new direction to critical sustainable development among developed countries.
