Research on Integrated Energy Services Evaluation System for the New Power System

This paper proposes an evaluation method of integrated energy service business development level for new power systems. Firstly, On the basis of analyzing the evaluation ideas of integrated energy service under the background of new power system, the evaluation index system is proposed from three dimensions: grid support level, economic benefit level and service friendliness level. Secondly, the corresponding evaluation method is proposed by using fuzzy principle. Finally, six typical integrated energy services such as integrated energy station, distributed photovoltaic, user-side energy storage, power trading agent service, comprehensive energy efficiency improvement service and electric vehicle charging service are selected for case verification. The proposed method can evaluate the development level of various subdivisions of integrated energy services under the consideration of the supporting role of the new power system, the characteristics of power enterprises, economic benefits and user experience, and provide a theoretical and practical basis for decision-making of integrated energy services under the new power system.
