Embodiment Construction
[0074] The present invention is further described below with reference to the accompanying drawings and specific examples:
[0075] A distributed power source pane-network method considering the source-responsiveness characteristics, including the following steps:
[0076] 1 establish a source of source side response resource model
[0077] Source-edge side can respond to resources to accommodate the power grid demand through its own operational conditions, mitigate the contradiction between supply and demand caused by distributed power and load side fluctuations. Responsive resources include a pumping energy storage power station that is grounded by the power supply side, a load side controlled response load and an active response load independently transferred according to the time-based electricity price.
[0078] 1.1 Pumped energy storage power station
[0079] The pumping storage power station is used as a power supply side resource that can simultaneously undertake power gen...

The invention relates to a distributed power supply grid connection method considering source load response characteristics, which is characterized by comprising the following steps of: classifying source load side resources, constructing an economic model of the source / load side resources participating in power grid operation according to the response characteristics of the source load side resources, and researching the distributed power supply grid connection problem by adopting a hierarchical optimization method. A source side distributed power supply and pumped storage access position is determined in a planning layer according to network loss sensitivity, load side controlled response load capacity is determined by considering economic cost, an operation layer is divided into different scenes according to various resource response capacities, and a source and load side resource synergistic effect is considered; and analyzing the effects of the power grid in the aspects of economic operation, new energy consumption, voltage stability and peak load shifting. Simulation analysis and verification are performed in combination with an actual power grid in a certain area, and the method has the advantages of scientificity, reasonability, quick calculation, accuracy, high efficiency, practicability and the like.
Description
Technical field [0001] The present invention belongs to the field of distributed power source, and is a distributed power supply grid approach considering the source of source response characteristics, through reasonable configuration of distributed power supply and source side resources in the grid, to comprehensively improve the comprehensive benefits of the grid. Background technique [0002] The penetration rate of distributed power supplies in the modern grid is continuously improved, and the amount of water storage power station, controllable load, etc., the source of source side resources, began to respond to the demand of the grid, and in terms of economic operation, gas-raising, peak-filled valley Play a positive role. Since various types of source, the resources have a unique configuration characteristic, and the increase in the penetration rate of source, and the complexity of grid planning and operation is increased. Therefore, it is of great significance for the deve...
