Embodiment Construction
[0064] Embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0065] A method to evaluate the impact of user electricity price design on the new energy consumption of the power system, such as figure 1 shown, including the following steps:
[0066] Step 1. Obtain the original power consumption data of users of different voltage levels in large industries and general industrial and commercial power grids in the area to be evaluated, and construct the daily typical power consumption curves of various users.
[0067] In this step, the method of constructing the daily typical power consumption curves of various users is to classify them according to different voltage levels from the daily load curves of many users obtained from the load control system, and select several typical power consumption curves from each voltage level. Users, and then follow the idea of from sample to population in statistics, ext...

The invention relates to a method for evaluating the influence of user electricity price design on new energy consumption of a power system. The method is technically characterized by comprising the following steps: constructing daily typical electricity consumption curves of various users; obtaining a current user electricity price structure of the to-be-evaluated regional power grid; constructing a function relation model between the electricity utilization behavior characteristics of various users of the to-be-evaluated regional power grid and the electricity price structure; solving the new energy consumption and utilization rate of the to-be-evaluated regional power grid; optimizing and adjusting the electricity price structure of the user; calculating typical electricity consumption curves of various users after optimizing and adjusting the electricity price structure; obtaining new energy consumption and utilization rate after optimization and adjustment of the power grid electricity price structure of the to-be-evaluated region; and comparing the difference between the new energy consumption amount and the utilization rate before and after optimization as the influence on the new energy consumption of the system after the electricity price of the user is adjusted. The method is reasonable in design, can reasonably optimize the peak-valley-flat electricity price level and time period of the user, and improves the new energy consumption level of the system.
Description
technical field [0001] The invention belongs to the technical field of electrical engineering, in particular to a method for evaluating the impact of user electricity price design on the consumption of new energy in a power system. Background technique [0002] At present, the power industry is actively building a new power system with new energy as the main body, and at the same time accelerating the deepening of power system reform, establishing a market mechanism that adapts to the new power system and promotes large-scale, high-proportion new energy consumption. The National Development and Reform Commission issued the "Notice on Further Deepening the Market-oriented Reform of On-grid Power Prices for Coal-fired Power Generation", orderly liberalized the on-grid power prices for all coal-fired power generation, expanded the fluctuation range of market transaction power prices, and promoted the entry of industrial and commercial users into the market. Catalog sales electr...
