Abstract
Double carbon background and the new energy power system policy, a large number of distributed photovoltaic access distribution networks have a great influence, not only on the low voltage distribution network user side power quality, but also on photovoltaic units, which are involved in the tide back phenomenon, for the stable operation of the medium voltage distribution network and scheduling. Therefore, this paper puts forward a scheduling of the voltage distribution network and low voltage distribution network optimization method, to solve the problems of large-scale distributed photovoltaic access.
From the perspective of improving the economic benefit of the distribution network and ensuring its safe operation, the medium and low voltage optimization model with the goal of reducing the operating cost is established.
The optimization problem of medium and low voltage distribution network is decomposed into the main optimization problems of medium voltage distribution network and the sub-problems of optimizing the low-voltage distribution network. An optimal solution is obtained by coordinating the boundary coupling variables between the two problems and solving them iteratively. Finally, the effectiveness of the coordination algorithm is verified by simulating the medium and low voltage distribution network.
The proposed method reduces the operating cost and ensures the stable and safe operation of the power grid, thus improving the economic benefits.
