Abstract

Similar to transmission network, distribution networks have the active management ability with high penetration of distributed renewable energy. The power exchange between transmission and distribution networks becomes flexible and bi-directional. In order to fully unlock the coordination capability of transmission-distribution interaction, this paper presents a flexible planning method for transmission network incorporating numbers of distribution networks with high penetration of renewable energy in the future. The coordinated optimization framework is a bi-level structure where transmission network planning is deployed in the upper level and distribution network operation is optimized in the lower level. The upper-level model delivers the locational marginal price to the lower-level model while purchase/sell agreement in reverse. The whole model is linearized using the piecewise linear approximation and big-M method. The original bi-level problem is transformed into a single-level equivalent using strong duality theory and then solved by off-the-shelf software. The case study carried out on the proposed high renewable energy penetration transmission network validates the effectiveness of the planning method, and further analyses the effect of transmission-distribution parameter on the planning results.
