Abstract

The invention discloses a marginal unit analysis method and device, and the method comprises the steps of determining a marginal unit through obtaining quotation information and node electricity priceinformation corresponding to output of each unit in a plurality of time periods, and determining the concentration degree of the marginal unit according to the distribution condition of the marginalunit; determining the load weight of each node, the determination degree of the marginal unit for the node electricity price of each node, calculating the energy consumption characteristic of each marginal unit, the high pricing information in the unit, and calculating the contribution degree of the marginal unit for the power market system and the Lenner index of the power market system. The marginal units are determined according to the quoted prices corresponding to the outputs of the multiple time periods and the node electricity prices corresponding to the multiple units, the calculationamount is small, and implementation is easy; in addition, the concentration degree, the high-pricing unit information, the contribution degree, the Lenner index and the like of the marginal unit can be effectively analyzed, and data support is provided for subsequent analysis of the power market system.

Description

technical field [0001] The invention relates to the technical field of electric power analysis, in particular to a marginal unit analysis method and device. Background technique [0002] With the continuous deepening and advancement of China's electric power reform, a number of power spot market pilots in China have been put into simulated trial operation one after another, and even carried out several settlement trial runs of different cycles. Market operators need to comprehensively and in-depth analyze the market operation. Data analysis excavates the characteristics of market operation, timely discovers whether there are problems in market operation, and reasonably analyzes the effectiveness of market mechanism design. Marginal unit analysis is a key link in market operation analysis and a core indicator for analyzing key information such as market pricing behavior, price fuel composition, and market competition effectiveness. [0003] The current perturbation method us...
