Embodiment
[0122] The embodiment of the present invention adopts the IEEE39 node 10 machine system as the test system, such as image 3 shown. Set nodes 30, 31, 32, 33, 34, 35, 36, and 37 as conventional thermal power units, nodes 38 and 39 as centralized access points for wind power, nodes 3, 4, 7, 8, 12, 15, 16, and 18 , 20, 21, 22, 24, 25, 26, 27, 28, 29, 31, 39 are load nodes. At the same time, the system is divided into two areas, and the load types and response characteristics in each area are different. Area 1 is set as a typical commercial and residential area, which is more sensitive to electricity prices and belongs to the price-sensitive area. In area 1, the proportion of loads responding to electricity prices is 40%, the elastic coefficient is -0.2, and the interactive potential range is [-50%, 50%], the proportion of responsive excitation load is 20%, the interactive potential range is [-50%, 50%], and the remaining 40% is rigid load whose power cannot be adjusted; area 2 ...
