Problems solved by technology

Time-of-use electricity price induces users to consume electricity as balancedly as possible with benefits, but end users have their own electricity consumption rules, and the induction effect is limited. Designing pumped energy storage power stations or installing peak-shaving units requires a lot of manpower and material resources, which is not economical

Abstract

The invention relates to an energy storage type power grid peak shaving system, which comprises energy storage equipment connected with a power grid, power grid peak shaving controllers II and a management platform. Each power grid peak shaving controller II is provided with a unique ID code. All the ID codes are uniformly grouped and managed by the management platform; the management platform receives a difference percentage difference value A between a real-time load of a current power grid and an expected load difference calculated by power grid dispatching and sends the difference percentage difference value A to the power grid peak shaving controller II; the power grid peak shaving controller II orderly charges the energy storage equipment according to the priority of the ID codes andgrouping under the instruction of the management platform difference value A so as to increase the power consumption of the power grid or feed back the power stored by the energy storage equipment tothe power grid. The bidirectional communication between the management platform and the power grid peak shaving controller II is utilized to realize that the power utilization end consumes more powerin the valley period of the power grid and consumes less power and feeds back power in the peak period, thereby reducing the peak-valley difference of the power grid, and enabling power generation, power supply and power utilization to be more stable, stable, safer and more economical.

Description

technical field [0001] The invention belongs to the technical field of electric power, and in particular relates to an energy storage type power grid peak regulation system. Background technique [0002] The peak-to-valley difference of the power grid is the difference between the maximum load of 100% and the minimum load as a percentage of the maximum load within a cycle of the power system. It is usually called the daily peak-to-valley difference in daily units, and there are also quarterly peak-to-valley differences and annual peak-to-valley differences. If the peak-to-valley difference of the power grid is too large, the operation of the power grid will be unstable and affect safe operation; the frequent start and stop of the peak-shaving unit will consume a lot of fuel for start-up and stop and stable combustion; the load of the thermal power generation unit in operation is unstable, It is necessary to adjust the heat load in real time, resulting in a decline in economi...
