Abstract

From the perspective of load planning, if the consumer has its own power generation facilities or energy storage devices, it can be somewhat complicated methodologically but can result in excellent outcomes. This paper proposes a load planning method in a time-of-use pricing environment assuming the consumer has both self-owned PV generation facilities and energy storage devices. The load is divided into fixed loads with a fixed consumption time and controllable loads with a flexible consumption time, and the controllable loads are the target of load planning. The goal of the proposed method is to minimize electricity bills while considering various realistic constraints such as precedence constraints between controllable loads. The proposed method uses mixed integer linear programming (MILP) as an optimization method and confirms its effectiveness by coding in Matlab.
