Power System Unit Commitment Incorporating Wind Energy and Battery Energy Storage

Abstract

In this paper, a probabilistic unit commitment model by incorporating wind energy and battery energy storage is developed, as well as a methodology based on forward dynamic programming with the aim of solving the problem. To test the model, a test system with four thermal generating units was used, including a wind farm and an energy storage system. The results of the simulation demonstrate the applicability and good performance of the proposed method and consequent decrease in pollution by using less fossil fuels. Besides, it shows the advantages of using energy storage systems to help at reducing the cost of unit commitment and make the system less susceptible to the uncertainties arising from the inclusion of wind power units in the power system.
