Active power distribution network coordination planning method considering multi-subject benefit game

Abstract

The invention relates to an active power distribution network coordination planning method considering a multi-subject benefit game. The method comprises the following steps of: firstly, determining respective objective functions and constraint conditions by taking the maximum annual net income as an objective of a network-source-load main body, and respectively establishing independent planning models of a network layer, a source layer and a load layer; then, an upper-layer strategy type game planning model is established with the fact that the three-party subjects achieve respective benefitbalance and stability in the game as an upper-layer target; taking the minimum reduction amount of the distributed power supply corresponding to wind curtailment and light curtailment as a target, andestablishing a lower-layer active management model by considering on-load transformer tap adjustment and energy storage adjustment; information transmission of the upper-layer game planning model andthe lower-layer active management model is considered, and a complete active power distribution network coordination planning model considering the multi-subject benefit game is established. The model established by the invention better adapts to maximization of benefit pursuits of all subjects in the gradually open power market, and the planning scheme solved based on the model can realize 'network-source-load' multi-subject friendly interaction and coordinate the overall planning.

Description

technical field [0001] The invention relates to an active distribution network coordination planning method considering multi-subject benefit game. Background technique [0002] Under the gradually open power market environment where the power sales side is released, large-scale access of distributed power sources and corresponding projects on the demand side are actively carried out, the planning of the active distribution network needs to take into account the access of distributed power sources and the impact of demand response. complex uncertain effects. At present, the main research content of active distribution network planning is focused on the following aspects: considering distributed power sources and load uncertainties to optimize distribution network planning, although "network-source-load" coordination is considered, planning decisions are concentrated on the grid side ; Coordinate and optimize the planning of distributed power generation and distribution netw...

Problems solved by technology

At present, the main research content of active distribution network planning is focused on the following aspects: considering distributed power sources and load uncertainties to optimize distribution network planning, although "network-source-load" coordination is considered, planning decisions are concentrated on the grid side ; Coordinate and optimize the planning of distributed power generation and distribution network, but does not involve the uncertainty brought by demand response at the load level; multi-objective optimization taking reliability, economy and renewable energy utilization effectiveness as considerations In planning, the weight between objectives is affected by subjective factors, and the planning method is to put two or three of the network layer, source layer, and load layer on a unified level for unified planning, without considering the network layer, source layer, and source layer in the open electricity market environment. The layer and the load layer may be the game decision-making behavior of multiple independent decision-making subjects
