Abstract:

Under the background of high-proportion grid-connected renewable energy in the future, the planning of multi-type adjusting resources in the power system is needed to improve the consumption of centralized and distributed renewable energy. This paper proposes a generation planning framework that considers the interaction process between transmission and distribution, and coordinates the capacity of source-load-storage resources in power system. Then, according to the distributed optimization theory, the model is decomposed into two planning sub-problems for transmission and distribution network. For the non-convex and nonlinear terms in the decomposed sub-program model, convex relaxation and linearization techniques are used to transform the model into a mixed integer second-order cone program for solution. Finally, this paper simulates the global system constructed by the IEEE 14-node system and the IEEE 33-node system to verify the effectiveness of the proposed model and optimization method, and analyzes the economy of the system and renewable energy consumption under coordinate planning.

Key words: renewable energy, source-load-storage overall planning, transmission and distribution network, distributed optimization, second-order cone relaxation
