Sitting Optimization of Soft Open Point Considering Operation Economy and Reliability of Micro-distribution Network
Aiming at the overall economy of the active distribution network containing multiple microgrids connected by soft open points (SOPs)
the sitting research is conducted. Firstly
the constraint model of the active distribution network containing SOPs under normal operation is established
and the objective function is set after fully considering the cost of real-time electricity price and the costs of the operation and maintenance of SOPs and energy storage batteries. On this basis
by relaxing and linearizing the original non-convex nonlinear constraints
a second-order cone programming model is obtained
which realizes the efficient solution of the nonlinear programming problem. Finally
the objective function is solved under the constraint conditions. The daily operation economy and node voltage deviation indices of the distribution network with different schemes are comprehensively compared
and the optimal sitting scheme of the SOPs is obtained
which verifes the significant advantages of SOPs in improving the economy and reliability of the micro-distribution network.
