摘要：

The joint optimization of power grid unit commitment and technical transformation plan considering transmission and distribution coordination is of great significance to improve the overall renewable energy consumption rate of transmission and distribution and ensure the medium- and short-term reliable and economic operation of the system. The joint optimization models of unit commitment and technical transformation plan of transmission network and distribution network are constructed respectively. Aiming at the problem of large randomness of renewable energy in medium- and short-term optimization，the opportunity constrained programming is adopted to transform the constraints into deterministic ones. The feasibility of discrete optimization，centralized collaborative optimization and distributed collaborative optimization of trans⁃ mission and distribution is analyzed，and the distributed collaborative optimization algorithm based on objec⁃ tive cascaded analysis method is used to realize the transmission and distribution decoupling and parallel calculation of the model after comprehensive comparison. Case analysis shows that the proposed model can reasonably arrange the unit start-up and shutdown states of transmission and distribution grids and the construction plan of technical transformation project，and the effectiveness of target cascaded analysis method in solving the transmission and distribution collaborative optimization problem is verified. © 2023 Electric Power Automation Equipment Press.
