Problems solved by technology

At present, most studies use the two-tier programming method to formulate planning schemes, but at the operational level, they usually only consider the network topology and distributed power supply operating costs, and rarely consider the impact of DR, especially transferable loads, on operation.
In addition, when modeling at the operation level, existing research lacks consideration of the impact of system flexibility requirements on distribution network planning

Abstract

The invention discloses a power distribution network double-layer planning method considering a system flexibility demand, which is applied to the technical field of power distribution network planning and specifically comprises the following steps: acquiring data, predicting, and generating a basic scene according to a prediction result; determining a planning layer objective function and constraint conditions, and constructing a power distribution network planning layer model; calculating the flexibility vacancy of each time node of the power distribution system according to the time sequence data of the prediction result; using the flexibility vacancy of each time node of the power distribution system to determine a simulation layer objective function and constraint conditions, and constructing a power distribution network simulation layer model; and solving the power distribution network planning layer model and the power distribution network simulation layer model by adopting a simulated annealing particle swarm algorithm to obtain a power distribution network planning scheme. According to the method, the power distribution network bilevel planning model considering the flexibility demand is established, consumption limiting factors can be reduced or eliminated as much as possible, the response potential of demand side response is further improved, the utilization efficiency of clean energy is improved, and the carbon emission cost and the network loss cost are reduced.

Description

technical field [0001] The invention relates to the technical field of distribution network planning, and more particularly to a double-layer planning method for a distribution network considering system flexibility requirements. Background technique [0002] New power system planning is an important technical prerequisite for leading the green and low-carbon development and transformation of the power system. As the main feature of the new power system, large-scale renewable energy grid connection makes the operation of the power system with significant uncertainty: large fluctuations in the output of renewable energy, serious local reverse transmission, and insufficient energy consumption efficiency. It brings great challenges and increases the difficulty of system planning. [0003] At the same time, the load exhibits the characteristics of initiative and complexity. The planning, operation, control and other aspects of the power system have undergone great changes. How...
