Embodiment Construction
[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0021] Method example:
[0022] This embodiment provides a smart distribution network load transfer method, such as figure 1 As shown, the method steps are as follows:
[0023] Step 1, obtain the primary model information of the distribution network system. Primary model information includes: plant information, voltage level, interval configuration information, equipment information, equipment connection relationship, etc.
[0024] Step 2, obtain the cross-sectional data of the distribution network system at the current moment from the distribution monitoring system. The cross-section data at the current moment includes: voltage, current, switch position, switch position, pressure plate status and equipment abnormal information of all equipment ...

The invention belongs to the technical field of distribution network system comprehensive automation, and relates to an intelligent distribution network load transfer method and device. This method first obtains the forecast data of the distribution network system in the future; then determines the operation topology of the distribution network system at the current time; combines the equipment operation status at the future time and the operation topology at the current time to obtain the abnormal topology of the distribution network system at the future time According to the abnormal topological nodes of the distribution network system in the future, several operating topologies of the distribution network system are re-determined, and corresponding load transfer strategies are generated; combined with the load of the equipment load in the future time of the distribution network system, the calculation of each The evaluation index of a load transfer strategy is used, and the load transfer strategy with the optimal evaluation index is taken as the load transfer strategy of the distribution network system. The invention can judge in advance whether the distribution network system needs to perform load transfer, and can perform load transfer in advance before equipment abnormality occurs, so as to realize active operation and maintenance.
Description
technical field [0001] The invention belongs to the technical field of comprehensive automation of distribution network systems, and in particular relates to a load transfer method and device for an intelligent distribution network. Background technique [0002] When the equipment in the smart distribution network is abnormal or will be abnormal, it is necessary to transfer the load of the abnormal equipment. At this time, operators expect to be able to quickly give decision-making schemes and load transfer schemes to ensure the healthy operation of the power grid. [0003] However, this scheme is to calculate the load transfer scheme when the equipment is abnormal, and the load transfer in the smart distribution network is a multi-objective optimization problem. and non-important loads, etc.), the network loss should be as small as possible, and the number of switching operations should be as small as possible, which puts forward requirements on the speed of the solution, ...
