Embodiment 1

[0129] 2.2.3 Clearing process

[0130] 1. Obtain power transaction information from the power trading platform, such as: market member (power generation company, power user, electricity sales company) number, market member name, market member's declared electricity price, market member's declared electricity quantity, and trading time;

[0131] 2. Obtain the power curves of market members from the power trading platform, including: typical power generation curves of power generation companies, typical power consumption curves of power users, and monthly declaration curves of power sales companies;

[0132] 3. Using the company (5)-(18), calculate the power generation and consumption curve correlation coefficient matrix λ between each power generation enterprise and all power users;

[0133] 4. With the formula (19) as the objective function and (20)-(27) as the constraint conditions, the linear programming method is used to solve the problem by using the linprog function of MA...

Abstract

The invention discloses a clearing method for considering a power generation side load curve matching degree for a medium and long term in electric power. The method comprises the steps of calculating a power generation and utilization curve correlation coefficient matrix lambda between each power generation enterprise and all power users; constructing an objective function and constraint conditions thereof; and solving the objective function, and obtaining the transaction electric quantity and the transaction price of each subject in each transaction pair when the transaction price difference considering the power generation side load curve matching degree is maximized. According to the clearing method for considering the power generation side load curve matching degree in the power medium and long term, through the clearing method for considering the power generation side load curve matching degree, it is guaranteed that power generation enterprises and power consumers with high power generation-power utilization curve similarity preferentially deal with each other, and it is guaranteed that the load curve is close to a power generation curve to the maximum extent.

Description

technical field [0001] The invention relates to a medium- and long-term electric power clearing method considering the matching degree of the load curve on the power generation side, and belongs to the technical field of electric power system automation control. Background technique [0002] In the power system, the power output and load must be balanced in real time, and the two curves are exactly the same in actual operation. However, with the incorporation of a large number of new energy sources, there are multiple power curves of power generation output characteristics in the power grid, and a single traditional load curve is still used, which cannot improve the traditional load characteristic indicators such as the peak-to-valley difference and load rate of the total load curve in the system at the same time. , but the output of conventional units fluctuates greatly and the level of new energy consumption is low. [0003] As of the end of June 2018, the installed capac...
