Research on Topology Design of User Side Energy Interconnection Network in Typical Environment

Abstract

The construction of smart green city promotes the development of efficient energy use. The development and utilization of user-side demand response resources has become one of the key and difficult problems to be solved urgently in urban sustainable development. This paper first analyzes the multi-dimensional decision-making of multi-objects such as energy demand, distributed renewable power, energy storage device, etc., and then analyzes the "incentive guidance-output correction" between the demand response implementer and the responder. The continuous and interactive process, and then proposes a two-layer topology model that uses the upper layer to guide the lower layer and the lower layer to feedback the upper layer to characterize the user side demand response. Consider the overall goal of maximizing social welfare based on cost considerations, and establish a two-layer topology model designed by user-side demand response incentive mechanism. The validity of the two-layer topology model proposed in this paper is verified by a numerical example. The benefits of the demand response and the influencing factors of the incentive mechanism are discussed. Based on this model, the topology design of the energy interconnection network is proposed. Principles and two new types of energy Internet topologies- the star topology of primary energy plus auxiliary energy and the ring topology with multiple distributed energy systems. Finally, a typical application scenario is selected for analysis and description of the user-side energy interconnection network topology in a typical scenario, and a feasible optimal configuration scheme and network topology are provided.
