New energy management approach in distribution systems considering energy storages

© 2017 IEEE. This paper presents a new method for energy management in distribution networks in the presence of energy storage, solar photovoltaic (PV) systems and diesel generators. Achieving optimal charge and discharge pattern for batteries and optimal diesel generator output with minimal operation cost are the main goal of this paper. The innovation of this paper is to consider the network effect on the underlying method with operational limitations and power-flow constraints such as power loss, voltage and current limitation. The proposed problem is solved for 24-hour time horizon, and the modified imperialist competitive algorithm (ICA) is also developed using mutation strategy to optimally solve the problem. Finally, to show the good performance and supremacy of the proposed method, a 33-bus IEEE standard test system is applied
