Renewable Generation and Transmission Expansion Planning Coordination with Energy Storage System: A Flexibility Point of View

This paper presents a method for coordinated network expansion planning (CNEP) in which the difference between total cost and flexibility benefit is minimized. In proposed method, generation (GEP) of wind farms with transmission (TEP) problem by using energy storage systems (ESSs) to improve flexibility. To consider impact reactive power CNEP problem, AC flow model used. The constraints include equations, different equipment, system operating limits. Therefore, this imposes hard nonlinearity onto linearized use first-order Taylor’s series big-M as well linearization circular plane. uncertainty loads, price, farm are modeled scenario-based stochastic programming (SBSP). determine effectiveness solution approach, it tested on IEEE 6-bus 24-bus test GAMS software.
