Energy deploying method and device in energy consumption system

Abstract

The invention provides an energy deploying method and device for an energy consumption system (e.g., an energy intensive enterprise) with a self-generating function. The method includes the following steps: based on energy consumption influencing factors, determining internal electricity prices of unit time periods in a future preset time interval; sending the internal electricity prices to power consumption units in the energy consumption system; the power consumption units determining electric-energy loads (e.g., power consumption time periods and power consumption quantities) in response to the internal electricity prices so as to enable the power consumption cost to be lowest, wherein the energy consumption influencing factors at least include scheduling of the power consumption units, the power consumption cost and a self-generating cost of the energy consumption system. The energy deploying method and device in the energy consumption system uses internal electricity prices to motivate the power consumption units in the energy consumption system to reduce as far as possible a power consumption expense which needs to be paid so that the energy cost of the whole energy consumption system is reduced to a specific degree.

Description

technical field [0001] The invention relates to the technical field of energy management and energy allocation, and in particular to an energy allocation method, device and management system in an energy consumption system with self-generating capacity. Background technique [0002] As the global energy shortage becomes more and more serious, the price of energy is also getting higher and higher. In order to save energy, most countries have promulgated their own series of energy-saving regulations. These regulations often lead to some energy-intensive enterprises (EIE: Energyintensive enterprises), such as metal smelters, chemical plants, and cement plants, in addition to facing higher and higher energy costs in production, they also need to meet at least government requirements. Formulated energy saving requirements. Therefore, how to reduce energy costs, especially electricity costs, is very important for energy-intensive enterprises. [0003] Usually, energy-intensive ...

However, this dynamic pricing mechanism of existing microgrids is not applicable to EIE microgrids

The reasons are: 1) In the EIE microgrid, different production schedules may lead to different loads of each power consumption unit, such as different sudden load demands; 2) Different power consumption units (production units) of the EIE microgrid ) are relatively closely related due to the constraints of the production schedule, so the load demand in the EIE microgrid is closely related to the correlation degree of each power consumption unit; 3) EIE microgrid to meet its own electricity demand is purpose; and 4) There is still great uncertainty in the power load in the EIE microgrid

Therefore, the existing dynamic pricing mechanism for general microgrids is not suitable for EIE microgrids
