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...

Abstract

The invention provides a method and a device for optimizing a direct transaction mode between a generating unit and a power consumer. The method comprises the steps of firstly determining all direct transaction modes between the generating unit and the power consumer; then determining wind-solar power abandoning quantity of a new energy generating unit or the sum of economic costs of the wind-solar power abandoning quantity and a thermal power generating unit under all direct transaction modes; and finally selecting the direct transaction mode with minimum wind-solar power abandoning quantityor the minimum value of the wind-solar power abandoning quantity and the economic cost as an optimal direct transaction mode. Different direct transaction modes are finally provided and optimization of different direct transaction modes is realized. The invention provides a direct transaction optimization model, compared with all direct transaction modes, the new energy consumption capability is improved and the economic cost of the thermal power generating unit is reduced.

Description

technical field [0001] The invention relates to new energy consumption technology, in particular to a method and device for optimizing the direct transaction mode between a generating set and an electric power user. Background technique [0002] As an important part of opening up the competition on the electricity sales side in the reform of my country's power market, the direct transaction of power users is the focus of the development of my country's power market. The existing trading rules are mainly based on bilateral negotiation and centralized matching. The bilateral negotiation transaction mode is within the scope of direct transaction electricity, the large users of access and the power generation enterprises directly meet the supply and demand, conduct direct transactions through bilateral independent negotiations, and pay the relevant transmission fees of the power grid operating enterprises at the same time, and transmit electric energy through public power networ...
