Implementation of battery management module for the microgrid: A case study

An optimal cost effective battery management strategy is developed for Microgrid based on a daily tariff from grid side. A Microgrid is an excellent frame work which gives a decentralized scheme to capitalize diverse renewable resources by cutting down power need of a consumer from the utility grid .Firstly, a daily price pattern of a load area is distributed into different regions for an average consumption of energy profile then the battery charging and discharging scheme is setup based on the availability of the renewable resources and the state of the charge .Real time 10min dispatch information send to Battery PCS through Modbus communication protocol and check the status of all generation and consumption units on graphical user interface developed in C#/Matlab. This proposed scheme is applied to the Beijing Goldwind Microgrid test bed which consist of Wind ,PV and Vanadium redox flow battery to supply power to a commercial building .The results are showing minimum dependencies on the grid power and utilizing all renewable and battery power at an optimum way.
