Optimal Electricity Procurement Plan for Charging Service Providers Gang Yu, Xianming Ye, Bo Wang

Abstract

This paper investigates the electricity procurement plan problem for charging service providers. The problem presents two challenges from both the demand and supply sides. On the demand side, the historical charging demand data is unavailable during the planning stage. On the supply side, multiple procurement options, including the spot market, financial power purchase agreements, self-invested power generation and energy storage are available on the market, with different costs, validity duration, and available capacities. To address these challenges, we propose a charging demand model to estimate demand at charging stations and develop cost models for various electricity procurement options. An optimization-based method to manage the electricity procurement portfolio is proposed. This method aims to minimize the total procurement costs while ensuring a reliable supply to meet the forecasted demand. The proposed approach is intended to guide charging service providers’ participation in the electricity market.
