Summary 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.

“…Integration of RESs with energy storage devices can maximize their output along with fulfilment of the load demand. 10 Depending on the availability of resources at the study sites, researchers have performed various studies. For example, a solar/wind/micro-hydro/diesel hybrid solution has been proposed for a remote and rural community in Orissa, India.…”

This study proposes an approach to determine the optimal placement and sizing of renewable distributed generations (DGs) and shunt capacitor in the distribution network (DN) with a pre‐defined energy contract strategy with the main grid by using fuzzy integrated mixed‐discrete particle swarm optimisation (MDPSO) based method. The proposed pre‐defined contract strategies are implemented in this study using the modified Newton–Raphson (NR) load flow method with the concept of the PQVδ−zero bus. The modifications in the Jacobian matrix in the NR load flow method is developed. MDPSO method is adopted to take care of both the continuous and the discrete variables, to determine the proper locations and the sizes of renewable DGs and shunt capacitor by reducing the active power loss, improving the voltage profile, and reducing the annual costs of the DGs. The multi‐objective optimisation is solved by using the fuzzy max–min‐based technique. The proposed method of DG placement is tested on 69 bus DN for three different scenarios. The results obtained from the proposed multi‐objective method are also compared with the weighted sum approach for different combinations.
