Optimization and planning of <scp>renewable energy sources</scp> based microgrid for a residential complex

World population growth and increased energy demand are taking a heavy toll on the environment. Aside from developed countries, adverse effects far more apparent in third-world which also affected by climate change, pollution, fuel scarcity. One of primary solutions to this challenge is implementation cleaner sustainable resources. Building scale renewable integration one included hybrid systems. The article aims design grid-tied system for residential complex Dhaka, Bangladesh. includes several combinations photovoltaic system, diesel generator, battery storage (BESS). key objectives analysis minimize costs, reduce grid dependency, emissions. Various models were simulated Hybrid optimization multiple resources (HOMER Pro) obtain suitable with maximum usage. Several systems compared based different parameters such as net present cost (NPC), operating cost, (COE), carbon A PV lithium was found be most powering load. From analysis, preferred can COE 53%, NPC 26%, costs 54%. Also, total emission reduced 31%. being cost-effective, proposed convenient sustainable, fewer salvageable parts owing its use lithium-based BESS.
