Abstract

In this paper, the optimal energy management considering battery characteristics for smart grid and micro grid systems is discussed. The energy storage system is very important for the energy peak shift and peak cut for micro grid and smart grid system because of these backgrounds. However, optimal battery formulation and energy management to suppress by using expensive energy storage system and considering battery characteristics are still in a developmental stage. First, the optimal battery placement for smart grid system with Lithium-ion battery is dealt with for lifetime extending. The battery choice index for this optimal battery determination problem to formulate optimal energy management is discussed. Second, the smart grid system with distributed battery system for grid frequency control considering distributed control and battery characteristics is dealt with. Optimal controllers for each distributed battery systems are designed to reduce battery load and to expend battery lifetime are designed. The effectiveness of the proposed method is shown via simulations by comparing with conventional methods.
