Method and system for simplifying point-to-point transaction network of partitioned power market

Abstract

The invention relates to a method and a system for simplifying a point-to-point transaction network of a partitioned power market. The method comprises the following steps of: 101, acquiring a power transfer distribution factor of each branch in the point-to-point transaction network of the power market by utilizing an active power increment of a node and an active power increment of each branch in the point-to-point transaction network of the power market; 102, simplifying the point-to-point transaction network of the power market based on the power transfer distribution factor of each branchin the point-to-point transaction network of the power market; and 103, if the simplified point-to-point transaction network of the power market is connected, outputting the simplified point-to-pointtransaction network of the power market, otherwise, reducing the power transfer distribution factor of each branch in the point-to-point transaction network of the power market and returning to the step 102. According to the technical scheme provided by the invention, various power transactions can be quicker and more intuitive, the purpose of effective analysis can be achieved, meanwhile, transaction information can be completely reserved, and the high efficiency and accuracy of security check load flow calculation are ensured.

Description

technical field [0001] The invention relates to the field of electric power automation, in particular to a method and system for simplifying a point-to-point transaction network in a regional electric power market. Background technique [0002] With the continuous maturity and development of the electricity market, electricity transactions are also growing. The result of power trading must meet the security constraints of the power grid to be effective. At this stage, domestic electricity transactions are carried out in point-to-point transactions in the regional electricity market. When dispatching agencies conduct security checks, they often face the problems of overly complex power grid networks, large calculations, and difficult maintenance of trading networks. Therefore, it is necessary to simplify the entire grid network for power trading. [0003] At present, the commonly used power grid network simplification methods include WARD equivalent method, REI equivalent m...

Problems solved by technology

However, the existing power grid network simplification method requires a clear division of internal and external regions, and power transactions are not concentrated in the same region, especially the cross-regional power transactions under the partition market model, which spread throughout the entire power grid network, and the regional boundaries are blurred. It is difficult to clearly divide the internal and external areas; at the same time, the existing grid network simplification method aggregates and simplifies the generators, loads, and congestion lines involved in the calculation of electricity prices as the main body of the bidding, and cannot completely retain transaction information, which affects the integrity of the transaction sex and correctness
