Abstract
Recently, there has been significant attention directed towards renewable energy sources, driven by advancements in power electronics, cost reductions, and escalating environmental concerns. The utilization of entirely renewable sources for fulfilling energy requirements presents advantages such as reduced energy costs, sustainable expenses, and local accessibility. This research assesses various scenarios encompassing diverse configurations to minimize greenhouse gas (GHG) emissions, cost of energy (COE), and annual net present costs (NPC). The evaluation considers factors like investment, replacement, decommissioning, operation, and maintenance costs. The study conducts an optimal power planning and techno-economic-environmental analysis of a grid-connected hybrid renewable energy system, incorporating elements such as wind turbines (WT), photovoltaic systems (PVs), diesel generators (DG), boilers, converters, thermal load controllers (TLC), and battery energy storage systems (BESS). The system is designed to cater to both electrical and thermal loads concurrently. The proposed methodology is tested using HOMER software on a small-scale system situated in Manjil, Iran, with a focus on its efficacy in meeting economic and sustainable electrical and thermal requirements within a hybrid renewable energy framework.
