The invention provides a distributive integrated energy supply system optimal configuration method considering a black-start function. The method comprises the following steps that: regional black-start scheme data is obtained, and the data includes system partitions, second-batch start power supply positions and capacities, start paths and the like; load data (load capacity and load value density) of each sub system (partition) is obtained; the black-start power supply type to be adopted by each partition and the reliability of the black-start power supply type are determined; the black-start reliability, the power failure loss and the black-start building and transformation cost are calculated in a quantified way; and an optimal mathematical model is built by using the power failure loss and black-start building and transformation cost weighing as a target and using technical indexes as constraints; and a PSO (Particle Swarm Optimization) algorithm is adopted for calculating the start power supply position and capacity of each sub system. The configuration method has the advantages that the reference can be provided for the planning and design of the distributive integrated energy supply system; the reference can be provided for the transformation of a black-start power supply; and the reliability of an electric power system can be improved.
Description
technical field [0001] The invention relates to the field of power system black-start power supply planning, in particular to the planning and design of a distributed integrated energy supply system as a black-start power supply. Background technique [0002] Distributed integrated energy supply system refers to the integrated application of primary energy conversion technology to provide users with multiple energies such as electricity, heat, and cold at the same time in one area, and realize cascaded and efficient utilization of energy. Due to its high efficiency and environmental protection performance, the distributed integrated energy supply system has been rapidly developed and used. [0003] The distributed integrated energy supply system has a fast startup speed and a fast output adjustment speed, which is a good black start power supply. For urban power grids lacking hydropower units, where the load density is high and units with self-starting capabilities are lack...
