Abstract

This paper evaluates the economic impacts of initial and final charges of battery energy storage (BES) devices on dispatch solutions when used in a multi-day and recurring operation. Two new modeling methods are proposed that have the ability of capturing the impacts of initial and final charges: one has a 2-day rolling scheduling window; and the other is a proposed model with a single day scheduling window, but incorporates the economic impact of ending charges on the next scheduling day. Numerical simulations are presented to illustrate their characteristics in term of dispatch solutions and economic impacts.
