Active distribution network expansion planning model considering low carbon and flexible load
Under the background of low-carbonization of distribution networks
an active distribution network expansion planning model that considers low-carbon and flexible loads is proposed. The objective is to provide the investment strategy with the minimum total cost under the premise of satisfying network operation constraints and CO2 emission limits. Decision variables include replacing overloaded lines
constructing new energy and energy storage devices
and constructing voltage control devices such as stabilizers and capacitor banks. The model proposes a polynomial form of voltage-related flexible load characteristics. To address the non-linear constraints in the flexible load model and network reconstruction constraints
the paper proposes a segmented McCormick envelope method and a virtual demand method to transform them into mixed-integer second-order cone optimization. Considering the uncertainty of new energy output
load
and energy prices
a two-stage stochastic optimization method based on scenario clustering is used for solving. The proposed model is tested on a 69-node system
