Problems solved by technology
[0003] Most of the existing market power assessment quantification techniques use the structural indicators, behavioral indicators and market performance indicators under the SCP model. These indicators do not take the elasticity of supply and demand into consideration in the monitoring process, and cannot fully reflect the exact situation of the electricity market. competition, and different indicators have different application time, scope and required data

The invention provides a power market competition degree measuring and calculating method and system based on a Panzar-Rosse model. The method comprises: acquiring reference data; establishing a Panzar-Rosse model, and determining a variable of the Panzar-Rosse model; inputting the reference data into a Panzar-Rosse model for regression analysis to obtain a parameter to be estimated; calculating result data according to the to-be-estimated parameters; and judging the market competition degree according to the result data. According to the invention, a Panzar-Rosse model (PR model for short) isused as a basis, a method for measuring and calculating the competitive degree of the electricity market is provided. The influence of investment unit price elements or other price influence elementsof a power plant on market revenue is emphasized, and the degree of market force is measured through the change degree of equilibrium revenue caused by the change of the unit price elements. The method can be combined with other market strength indexes to effectively measure and calculate the market strength pattern in the electricity market.
Description
Technical field [0001] The invention relates to the technical field of power markets, and in particular to a method and system for measuring the degree of competition in the power market based on a Panzar-Rosse model. Background technique [0002] With the advancement of power market reforms, the construction of the power spot market has gradually been put on the agenda. The characteristics of high-frequency trading and marginal constraint pricing in the spot market make market power more likely to be abused, thereby affecting the fairness of competition, and power resources cannot be effectively and reasonably allocated. To ensure the healthy and stable operation of the electricity market, regulatory agencies must use scientific methods or technologies to quantify the degree of market competition and the market power of market entities. [0003] Most of the existing quantitative techniques for evaluating market power use structural indicators, behavioral indicators, and market pe...
