The invention provides a load area determination method, comprising the following steps: calculating a preset market clearing model by utilizing a mixed integer programming algorithm to obtain a power flow relaxation amount and a relative out-of-limit degree of each blocked line, and taking the blocked line with the maximum relative out-of-limit degree as a target line; setting the target lines as power flow hard constraints, performing cyclic calculation on the market clearing model until all the target lines are determined, and taking all the target lines as boundary lines of the load area; and determining each load area based on the boundary lines. According to the data processing method, the boundary line is determined according to the power flow relaxation amount and the relative out-of-limit degree of each blocked line, and the power flow relaxation amount and the relative out-of-limit degree can reflect the blocking condition of the network line, so that the data processing method can determine the load area which is not blocked by the network line and is connected with each node in the area. The invention further provides a load area determination system and device and a computer readable storage medium which all have the above beneficial effects.
Description
technical field [0001] The present application relates to the field of load area determination, in particular to a load area determination method, system, device and computer-readable storage medium. Background technique [0002] The power industry system is undergoing profound changes. It has become a development trend to break monopoly, introduce competition, and establish a unified, open, competitive and orderly power market. The spot market is an important part of the electricity market system, which plays a fundamental role in supporting the openness, competition, and orderly operation of the electricity market, and is also the key to coordinating market transactions and system security. [0003] Under the pricing mechanism of the spot market, the entire network needs to be divided into several load areas, that is, to determine the load area. At present, the method of determining the load area is to cluster based on the node electricity price, and take the area where t...
