Energy storage systems are becoming more and more important for integrating higher levels of varying and intermittent renewable power into the grid. As we have energy storages with different characteristics and applications, hybrid storage solutions combining various technologies to meet different applications are fast developing. In this paper, an efficient energy management strategy is proposed for a VRB and Li-ion hybrid battery system to be integrated with a grid-connected wind-PV Hybrid Renewable Energy System (HRES). The operation of the generating system and the storage batteries are evaluated using Matlab/Simulink and techno-economic analysis is carried out. The results demonstrated successful implementation of the hybrid system with improved deliver ability and storage lifetime. © 2019 Elsevier Ltd

The power consumption has increased enormously due to the intervention of high end technology and it is necessary to meet this power demand. The power pushed into any electrical system should be highly reliable, secured with sufficient quantity and quality. One such solution is to bring reliable and flexible power by introducing Hybrid energy systems into the network. The main motivation of hybrid energy systems is to improve the delivery of power at the utilities and customer end. In this paper, a complete literature review is made on the integration of solar photovoltaic, wind and diesel generator with energy storage systems like hydrogen based fuel cells and batteries. This hybrid system reduces the operating time of diesel generator, save the fuel consumption and hence accomplishes the peak demand with diesel generator. © 2018 Eastern Macedonia and Thrace Institute of Technology.

A Bibliographical Survey on Integration of Hybrid Renewable Energy Sources with Diesel Generator and Storage System

This paper proposes an intelligent battery management system (BMS) implementing two large Vanadium Redox Battery (VRB) flow batteries in a master-slave mode to provide grid-level energy storage for a wind-solar hybrid power system. The proposed BMS is formulated to effectively meet a predetermined power dispatch formulated based on forecasted wind and solar data while incorporating features like peak shaving and ramp rate limiting. It is compared to a single battery module operated system to showcase the advantages of the proposed intelligent dual battery module in terms of appreciable reduction in battery size and costs while exhibiting improved lifecycle performance. The battery size is optimized based on heuristic optimization algorithms and modelled in Matlab/Simulink environment. An intelligent fuzzy-based BMS is used to control the dual VRB model to ensure optimized power sharing between batteries. The simulations were carried out and an in-depth economic analysis conducted to analyze the costs and other financial metrics of the hybrid project. Results proved the advantages of the dual battery with the proposed BMS and fortify that the introduction of time-based tariffs and other incentives will further make investments in VRB highly attractive for renewable applications.

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.
