摘要

可再生能源因其低排放、可持续性和经济基础而被认为是环保的。该研究的重点是在巴基斯坦不同气候带的住宅部门实施本土可再生能源发电。本研究进行了技术经济、环境、稳健和成本分析。技术经济优化是为了最小化净当前成本（NPC）、平准化电力成本（COE）和最大化住宅微电网的可再生部分（RF）。中部和北部地区具有可行的太阳辐照度剖面。在这种情况下，最好的MG配置是PV-BESS和DG。而对于南方地区，风廓线是有利的。因此，大多数地区的最优MG配置为PV-WT-BESS。对仅使用柴油发电机（DG）满足负荷需求的基本情况和同时使用可再生能源和DG的建议情况进行了比较。结果表明，加入可再生能源后，除了降低NPC和LCOE外，还能减少温室气体排放，提高可再生能源的比例。这使我们实现了可持续发展目标7和13。在这种情况下，对公用事业组合进行了另一种比较。第一种配置有燃气和电力公用设施，而其他配置只有电力公用设施，以满足负荷需求。结果表明，该方法提高了电力利用效率和经济性。

Techno-economic analysis and optimization of renewable sources and battery energy storage system across diverse climatic zones considering gas and electrical utilities

Renewables are considered eco-friendly due to less emission, sustainability, and economical basis. The study focuses on implementation of indigenous renewable generation sources across residential sector of different climatic zones of Pakistan. This study carried-out techno-economic, environmental, robust, and cost analysis. Techno-economic optimization is performed to minimize net present cost (NPC), Levelized cost of electricity (COE) and to maximize renewable fraction (RF) for micro grid of a residential sector. Central and North region has a viable profile for solar irradiance. On that account best MG configuration is PV-BESS along with DG. While for South region wind profile is profitable. So optimum MG configuration in most regions is PV-WT-BESS. A comparative comparison is made for base case having just diesel generator (DG) to fulfil load demand and proposed case having renewables along with DG. Results shows that by adding RERs not only Greenhouse gas emissions are minimizing but also renewable fraction is increased besides minimizing NPC and LCOE. This led us to satisfy SDG-7 and SDG-13. In proposed case another comparison is made between combination of utilities. First configuration has both gas and electrical utility while other has just electrical utility to fulfil load demand. Results show that electrical utility is more efficient and economical.

期刊介绍： The journal Energy Conversion and Management provides a forum for publishing original contributions and comprehensive technical review articles of interdisciplinary and original research on all important energy topics. The topics considered include energy generation, utilization, conversion, storage, transmission, conservation, management and sustainability. These topics typically involve various types of energy such as mechanical, thermal, nuclear, chemical, electromagnetic, magnetic and electric. These energy types cover all known energy resources, including renewable resources (e.g., solar, bio, hydro, wind, geothermal and ocean energy), fossil fuels and nuclear resources.
