Energy storages are emerging as a predominant sector for renewable energy applications. This paper focuses on a feasibility study to integrate battery energy storage with a hybrid wind-solar grid-connected power system to effectively dispatch wind power by incorporating peak shaving and ramp rate limiting. The sizing methodology is optimized using bat optimization algorithm to minimize the cost of investment and losses incurred by the system in form of load shedding and wind curtailment. The integrated system is then tested with an efficient battery management strategy which prevents overcharging/discharging of the battery. In the study, five major types of battery systems are considered and analyzed. They are evaluated and compared based on technoeconomic and environmental metrics as per Indian power market scenario. Technoeconomic analysis of the battery is validated by simulations, on a proposed wind-photovoltaic system in a wind site in Southern India. Environmental analysis is performed by evaluating the avoided cost of emissions.

Recent attention to industrial peak shaving applications sparked an increased interest in battery energy storage. Batteries provide a fast and high power capability, making them an ideal solution for this task. This work proposes a general framework for sizing of battery energy storage system (BESS) in peak shaving applications. A cost-optimal sizing of the battery and power electronics is derived using linear programming based on local demand and billing scheme. A case study conducted with real-world industrial profiles shows the applicability of the approach as well as the return on investment dependence on the load profile. At the same time, the power flow optimization reveals the best storage operation patterns considering a trade-off between energy purchase, peak-power tariff, and battery aging. This underlines the need for a general mathematical optimization approach to efficiently tackle the challenge of peak shaving using an energy storage system. The case study also compares the applicability of yearly and monthly billing schemes, where the highest load of the year/month is the base for the price per kW. The results demonstrate that batteries in peak shaving applications can shorten the payback period when used for large industrial loads. They also show the impacts of peak shaving variation on the return of investment and battery aging of the system.

The electric power system is undergoing important changes and updates nowadays, particularly on a generation and transmission level. Initially, the move towards a distributed generation in distinction to the present centralized one implies a major assimilation of energy from undeleted supply and electricity storage systems. Advanced power physics interfacing systems are expected to play a key role within the development of such modern governable and economical large-scale grids and associated infrastructures. Throughout the last era, a worldwide analysis and development interest has been impressed within the field of segmental structure conversion; thanks to the well-known offered blessings over typical solutions within the medium and high voltage and power range. Within the context of battery energy storage systems, the segmental structure conversion device family exhibits a further attraction, i.e., the aptitude of embedding such storage parts in an exceedingly split manner, given the existence of many submodules operative at considerably lower voltages. This study deals with many technical challenges related to segmental structure converters and their development with battery energy storage parts to boost load sharing system.
