Embodiment 1
[0106] Embodiment 1 of the present invention provides an optimization method for the direct transaction mode between a generating set and an electric power user. The specific flow chart of the optimization method is as follows figure 1 As shown, it specifically includes the following steps:
[0107] S101: Determine all direct transaction methods between generating units (including new energy units, thermal power units and wind power units) and power users;
[0108] S102: Determine the sum of the abandoned wind and solar energy of new energy units or the sum of the abandoned wind and solar energy and the economic cost of thermal power units under all direct transaction methods;
[0109] S103: Select the direct transaction method with the smallest amount of wind and solar curtailment or the smallest sum of wind and solar curtailment and economic cost as the optimal direct transaction method.
[0110] In the above S101, all direct transaction methods between generating units and...
Embodiment 2
[0186] As of the end of June 2016, the installed capacity of wind power in a province in my country was 12.7223 million kilowatts, accounting for 26.90% of the total installed capacity of the system; the installed capacity of photovoltaics was 6.7777 million kilowatts, accounting for 14.33% of the total installed capacity of the system; %, this province is an area where the contradiction of abandoning wind and solar is more prominent in China. Therefore, this province is taken as a typical province to study the optimization method of direct transaction of electricity users to promote the consumption of new energy. After sorting out, there are 39 thermal power units in this calculation example, including 2 thermal power units of 600MW, 2 units of 660MW, and the rest are 330MW and below. The characteristics of the units are shown in Table 1. According to the characteristics of the units, The units are divided into 4 categories. Type I units represented by Nos. 1, 2, 3, and 4 have...
