Optimal Scheduling of Micro-Grid Multi-Energy System Considering Two-Dimensions Price-Based Demand Response

Abstract

The demand response realizes the flexible energy utilization on the user side and promotes the energy utilization efficiency in the multi-energy micro-grid system. This paper establishes a two-dimensions price-based demand response model with both vertical load transfer and horizontal energy conversion. Considering a variety of renewable energy resources and energy storage, this paper studies the optimal scheduling of multi-energy micro-grid system with the feedback of residual power sold to the external grid, so as to maximize the revenue of a multi-energy micro-grid system operators. A case study shows that the two-dimensions price-based demand response can not only effectively reduce the energy consumption cost of users, but also improve the benefits of multi-energy micro-grid system.
