A Multi-objective Orderly Power Sorting Method Based on Electricity Characteristics

Abstract

The invention provides a multi-target orderly power utility ordering method based on power utility characteristics, accurately calculates user division load characteristic data, assesses power rationing effects of different orderly power utility schemes, and optimizes the orderly power utility scheme. In an off-peak scheme, users are sequentially ordered according to values of off-peak indexes. The larger the index is, the off-peak effect is better. A user with a large off-peak index is given priority to off-peak power rationing. In a rest-shifting scheme, ordering is based on values of peak-shifting indexes. A user with a large peak-shifting index is given priority to rest-shifting power rationing. In a time-staggering scheme, ordering is based on values of time-staggering indexes. A user with a large time-staggering index is given priority to time-staggering power rationing. The multi-target orderly power utility ordering method is advantaged in that three indexes are adopted to respectively indicate power rationing effects of users at different peak-shifting and off-peak measures, an orderly power utility effect assessment system is established by considering many factors such as clients, social economy and electric quantity, differences of users in the orderly power utility effect are quantified, and a decision basis is provided for the establishment of the orderly power utility scheme.

Description

technical field [0001] The invention relates to a multi-objective orderly power consumption sorting method based on power consumption characteristics, which belongs to the field of electric power. Background technique [0002] With the further deepening of the contradiction between power supply and demand in our country, strengthening power demand side management has become an urgent task for all power companies. Faced with periodical power shortages, especially peak loads in summer, power grid enterprises can only rely on orderly power consumption for management when existing demand-side management methods cannot fully balance power supply and demand. [0003] In order to ensure the safe and stable operation of the power grid and ensure the order of social power consumption, the National Development and Reform Commission, the State Grid Corporation of China and the Jiangsu Provincial Electric Power Company have all issued the "Orderly Power Consumption Management Measures"....

AI Technical Summary

Problems solved by technology

[0006] 1. The load characteristics data of enterprise users are mostly determined by communication and experience, and cannot truly reflect the load characteristics of enterprise users, such as enterprise user security load, limitable load, peak load, etc.

[0007] 2. The existing orderly power consumption plan formulation model lacks analysis and evaluation methods for the effect of power cuts

The existing orderly power consumption plan only considers whether the plan can finally meet the power limit load index issued by the government, and does not evaluate the impact on other socio-economic, government, and power grids, which leads to bargaining in the process of formulating and implementing the plan and affects the quality of the plan. fair and equitable

[0008] 3. Orderly power consumption is a problem of multi-condition constraints and multi-objective decision-making. The existing model is a single-objective decision-making, which makes it difficult to maximize the multi-objective comprehensive benefits of power supply companies, governments and enterprises.

The existing preparation mode only considers the limitable load of the user itself, and takes whether to complete the power gap index value issued by the government as the program evaluation goal, without considering the impact on corporate customers and social economy, and cannot achieve multi-objective decision-making
