Regional Integrated Energy System Day-ahead Optimal Dispatch Considering Carbon Emission

Abstract

In the integrated energy system(IES), the complementary characteristics of the power and heat systems play a role in increasing the flexibility of the system operation. In addition, it can be valid to take carbon emissions into account to reduce carbon dioxide emissions, thus weakening the greenhouse effect and implementing the "double carbon" development goal of China. To this end, we set up a day-ahead optimal dispatching model for IES considering carbon emissions to analyze the impact of carbon emissions on the economic operation of the system and the environment. This model aims at minimizing system operation costs. It introduces carbon emissions costs while avoiding wind and photovoltaic (PV) power generation abandonment as far as possible. It takes system safety and equipment capacity as constraints. Besides, particle swarm optimization is a potent way of dealing with this problem. Finally, the example proves that the proposed approach is resultful, whether in improving energy efficiency or reducing carbon emissions.
