Demand side response potential assessment method and system considering user load characteristics

Abstract

The invention discloses a demand side response potential evaluation method and system considering user load characteristics, and the method comprises the steps: selecting proper demand side response triggering time according to the total load data and new energy power generation data of regional large power users; according to the demand side response triggering time, calculating the peak load rate of each large power user in the region in the demand side response time period, analyzing the minimum peak load rate of each large power user on the premise of normal production on the basis of the peak load rate, and calculating the load capacity of the large power users participating in the demand side response to the maximum extent; uniformly allocating the load capacity responded by the demand side to each demand side response time period, forming a power load curve after power demand side response, and achieving power supply and demand balance relation evaluation through the power load curve after power demand side response. A load curve after demand side response is truly simulated, and reference is provided for safe and stable operation after demand side response of a power system.

Description

technical field [0001] The invention belongs to the technical field of planning and operation evaluation in electric power systems, and in particular relates to a demand side response potential evaluation method and system considering user load characteristics. Background technique [0002] Electricity demand-side response means that when the electricity market price rises significantly (decreases) or the safety and reliability of the system is at risk, the electricity users change the inherent power consumption mode and reduce (increase) electricity consumption according to the price signal or incentive measures, thereby promoting the power supply and demand. Balance, maintain system reliability and improve system operating efficiency. [0003] In recent years, with the development of the economy and society and the increase in electricity consumption, there is a shortage of electricity in some areas during the peak period of electricity consumption in various regions.

Problems solved by technology

In the conventional evaluation method currently used, the load characteristics of the user side are not considered comprehensively. Due to the different production processes and industrial properties of the major electricity industries, the load characteristics are different, and the peak shaving capabilities are also different. When analyzing the response capabilities of the demand side Neglecting the key information of the load characteristics, it is impossible to accurately evaluate users with strong responsiveness and large scale, which brings unnecessary risks to the reliable operation of the power system and increases the operating efficiency of the power system
