Microgrid systems based on renewable energy sources can play a significant role in providing cost‐effective, environmentally friendly and reliable electrical supply to the people living in rural areas of India. This assessment aims to design and evaluate the performance of a grid‐connected microgrid system comprising of photovoltaic (PV) arrays, wind energy generating units and battery energy storage system (BESS). The realistic load data of a small village, Tandwal, located in Ambala district of Haryana, India, is considered for this assessment. Furthermore, sensitivity analysis is performed to find out the effect of load demand, solar radiation, utility grid price, grid outages, capital cost of BESS, solar module cost and power converter loading ratio in the proposed microgrid system. The results show that the PV‐BESS‐utility grid system is an optimal solution with renewable energy penetration at the studied location. The feed‐in tariff/net metering makes the overall system sustainable and improves its reliability with unmet load as well as capacity shortage.

可靠农村电气化微电网系统的设计与分析

基于可再生能源的微电网系统可以在为印度农村地区的人们提供经济高效，环保和可靠的电力供应方面发挥重要作用。该评估旨在设计和评估由光伏（PV）阵列，风力发电单元和电池储能系统（BESS）组成的并网微电网系统的性能。该评估考虑了位于印度哈里亚纳邦安巴拉地区的一个小村庄坦德瓦尔的实际负荷数据。此外，进行敏感性分析以找出所提出的微电网系统中负载需求，太阳辐射，公用电网价格，电网中断，BESS的资本成本，太阳能组件成本和功率转换器负载比的影响。结果表明，PV-BESS-公用电网系统是在研究位置具有可再生能源渗透的最佳解决方案。馈电费率/净计量使整个系统具有可持续性，并在未满足负载和容量不足的情况下提高了可靠性。
