Problems solved by technology

[0003] Since large-scale clean energy is mostly far away from the load center, limited by the load level of the regional power grid and the structure of the power supply, the pressure on dispatching operation and acceptance of clean energy is huge, and the abandonment of wind and water is serious.
As the proportion of clean energy continues to grow, it is difficult to achieve local consumption of clean energy. Traditional power trading does not take into account the differences in power structure and load distribution in geographical regions, nor can it conduct cross-regional trading of electric energy and a wide range of clean energy. Consumptive

Embodiment 1

[0061] Such as figure 1 Shown:

[0062] Step 1: Obtain the comprehensive pair of electricity sellers and the comprehensive pair of electricity buyers in each region according to the declaration pairs of electricity sellers and declaration pairs of electricity purchasers in each region;

[0063] Step 2: Bring the inter-regional connection, the comprehensive pair of electricity sellers and the comprehensive pair of electricity buyers in each region into the pre-set cross-regional transaction optimization model, and obtain the: cleared electricity price, final price of each electricity seller Electricity sales and final electricity purchases by each electricity purchaser;

[0064] Step 3: Carry out cross-regional transactions according to the clearing electricity price in the area and the area connected to the area, the final electricity sales of the electricity seller, and the final electricity purchase of the electricity buyer.

[0065] The above-mentioned steps are further e...

Embodiment 2

[0116] The design method of the multi-regional electric energy trading mechanism for the cross-regional consumption of clean energy in the present invention includes the following steps: figure 2 Shown:

[0117] Determine the number A of regions participating in clean energy cross-regional transactions, as well as the connection of regions and the transmission cost of connected regions. And use (a,b)∈L to represent the connection between region a and region b, where a,b=1,2,...,A represents the region index; the transmission cost of the connected region is represented by C ab express.

[0118] For each region, each electricity seller (for example, a clean energy power generation company) declares (sales electricity, electricity price) pairs for a certain period of time, using means; at the same time, each electricity purchaser (for example, a clean energy power generation company) declares (purchased electricity quantity, electricity price) pair for the same time period, u...

Embodiment 3

[0163] The present invention also relates to a multi-area electric energy trading system, comprising:

[0164] Acquisition module: used to obtain the comprehensive pair of power sellers and the comprehensive pair of power purchasers in each region for the declaration pair of power sellers and the declaration pair of power purchasers in each region;

[0165] Obtaining module: it is used to bring the inter-regional connections, comprehensive pairs of power sellers and comprehensive pairs of power buyers in each region into the pre-set cross-regional transaction optimization model, and obtain: The final electricity sales of each party and the final purchase of electricity by each purchaser;

[0166] The cross-regional transaction module includes: used for cross-regional transactions according to the clearing electricity price in the region and the region connected to the region, the final electricity sales of the electricity seller, and the final electricity purchase of the elect...

Abstract

A method and system for trade multi-area electric energy includes declare pair of electric power seller and declare pair of electric power purchaser for each area to obtain comprehensive pair of electric power seller and comprehensive pair of electric power purchaser for each area, declare pair of electric power seller and purchaser for each area, declare pair of electric power purchaser for eacharea to obtain comprehensive pair of electric power seller and purchaser. The connection between regions, the power sellers and the power purchasers in each region are integrated into the preset cross-regional transaction optimization model, and the internal ones of each region are obtained as follows: the clearing price, the final power sales volume of each power seller and the final power purchase volume of each power purchaser; According to the clearing price of electricity in the region and the region connected with each other, the final sale quantity of electricity by the power seller andthe final purchase quantity of electricity by the power purchaser are transacted across regions. A method and system for design a multi-region electric energy trading mechanism Considering the difference of power structure and load distribution in the geographical region, it is helpful to promote the lower generation cost, lower load level of the region to higher discharge cost, higher load levelof the region to transfer electric energy, to achieve the optimal allocation of power generation resources in a larger range.

Description

technical field [0001] The invention belongs to the field of power system energy consumption, and in particular relates to a multi-regional power trading method and system. Background technique [0002] In recent years, the wind power grid-connected capacity has grown rapidly, and the installed capacity of wind power has ranked first in the world for many years. In 2016, the newly installed wind power capacity was 23.37 million kilowatts, and the cumulative grid-connected installed capacity reached 169 million kilowatts. The large-scale grid integration of clean energy such as wind power also brings a series of consumption problems. [0003] Due to the fact that large-scale clean energy is mostly far away from the load center, limited by the load level of the regional power grid and the power structure, the pressure on dispatching operation and clean energy acceptance is huge, and the abandonment of wind and water is serious. As the proportion of clean energy continues to ...
