Comprehensive Energy Planning Method Based on Multi-energy Complementarity of User Side

Abstract

The planning and design of multi-energy complementary energy system is the primary key technology to ensure its safe, economic and reliable operation. Since the multi-energy complementary micro-grid contains various energy sources such as heat source and power source, and various types of energy-using loads such as heat load and electric load, the source, network and load have strong coupling relationship, and the renewable energy sources such as solar and wind have strong volatility, and the system operation scenarios are complex and diverse, it is difficult to apply the conventional planning methods directly. Therefore, in this paper, we propose a multi-energy complementary micro-grid planning method that considers the coordinated interaction of source, load and storage in detail, fully accounts for the uncertainties on the source and load sides and the coordinated coordination of multiple energy flows, establishes a user-side demand response model, which fully considers the operational constraints of interruptible load, transferable load and user satisfaction; proposes a dual-layer planning method, and proposes a black-box time-consuming solution method for the solution of the dual-layer optimization model, which effectively ensures the rapid solution to obtain the planning capacity of renewable energy sources, cogeneration units, thermal and electrical energy storage systems and other devices.
