Low-Carbon Economic Dispatch of Integrated Energy System Based on IGDT Robust Model

Abstract

In recent years, under the goal of carbon peaking and carbon neutrality, the research on integrated energy "source, network, load and storage" has been the main battlefield for carbon reduction. The carbon reduction path of regional integrated energy system is analyzed and the overall planning is carried out which is an important way to reduce carbon emissions in the power industry. However, the output of wind power and photovoltaics is volatile, which poses a great challenge to the stability and economy of the integrated energy system. In order to improve the low-carbon and economical operation of the integrated energy system, this paper proposes a new type of energy multi-energy complementary system to solve the problem of wind and solar output fluctuations in the regional integrated energy system, integrates and optimizes the energy supply system. First, an optimization model of the regional comprehensive energy system is constructed. On this basis, the optimization goal is to minimize the sum of energy purchase cost, carbon transaction cost, equipment operation and maintenance cost, and daily purchase cost. Aiming at the output volatility of wind power and photovoltaics, the information gap decision theory (IGDT) is used to describe the fluctuation range, which provides a basis for energy service providers to control equipment. The result analysis verifies the low carbon and economical properties of the planning model.
