Embodiment 1

[0093] This embodiment provides an energy regulation system, which can optimize the energy flow of the controlled system in combination with weather forecast information and the parameters of the controlled system, so that the controlled system is in the optimal operating state and the benefit is maximized, and the entire system is realized. to maximize the comprehensive benefits.

[0094] Such as figure 1 As shown, the energy regulation system includes: a controlled system 100 , an energy regulation device 200 and a weather server 300 .

[0095] The controlled system 100 includes: a power generation device 110 , an energy storage device 120 and an air conditioner 130 . The power generation equipment, the energy storage equipment and the air conditioner are connected in parallel through a DC bus (including a positive bus DC+ and a negative bus DC-). The air conditioner is also connected to the AC grid 400 (ie, the mains grid). The controlled system is an integrated system o...

Embodiment 2

[0113] Based on the same idea, this embodiment provides an energy regulation method, the method is applied to the energy regulation system described in the above embodiment, and the method can be executed by an energy regulation device. Such as Figure 4 As shown, the method includes:

[0114] S401. Obtain weather forecast information within a preset time period in the future in the area where the controlled system is located.

[0115] Wherein, the future preset time period may be set according to actual needs, for example, the next 6 hours or the next 3 days. The maximum value of the future preset time period is the forecast duration provided by the weather forecast, that is, the future preset time period can be any value within the forecast duration.

[0116] S402. Determine an optimal energy flow configuration of the controlled system within the future preset time period according to the weather forecast information and the current energy storage information of the contro...

Embodiment 3

[0181] The above-mentioned energy regulation system and method will be described below in conjunction with a specific embodiment. However, it should be noted that this specific embodiment is only for better illustrating the present application, and does not constitute an improper limitation of the present application. Explanations of terms that are the same as or corresponding to those in the foregoing embodiments will not be repeated in this embodiment.

[0182] In this embodiment, the integrated system of photovoltaic, energy storage, and air conditioner compressor is used as an example to illustrate the controlled system. The controlled system has both power storage and cold storage functions.

[0183] refer to Figure 5 , is a schematic structural diagram of the energy flow intelligent decision-making system (equivalent to the above-mentioned energy regulation system) of the photovoltaic, energy storage, and air-conditioning compressor integrated system, including:

[018...

Abstract

The invention discloses an energy regulation system, method and device. Wherein, the energy regulation system includes: a controlled system, an energy regulation device and a weather server; the controlled system includes: a power generation device, an energy storage device and an air conditioner; the power generation device, the energy storage device and the air conditioner The equipment is connected in parallel through the DC bus; the air conditioner is also connected to the AC power grid; the energy regulation device is respectively connected to the controlled system and the weather server, and the energy regulation device is used to obtain the future from the weather server Weather forecast information within a preset time period, and send the optimal energy flow configuration within the future preset time period to the controlled system. Based on weather factors, the invention can realize the optimal operation state and maximize the benefit of the controlled system in the future preset time period; the DC bus is used to gather loads together, which can reduce system energy consumption and system complexity.

Description

technical field [0001] The present invention relates to the technical field of energy regulation, in particular to an energy regulation system, method and device. Background technique [0002] At present, for the integrated system of power generation, energy storage and energy consumption, for example, in the integrated system of photovoltaic, energy storage and air conditioning, the energy flow control among the city grid, energy storage, photovoltaic and air conditioning compressor is a comprehensive peak, The valley electricity price and the energy consumption law of the air-conditioning system regulate the energy flow between photovoltaics, energy storage, and city grid. It is the power balance between the power supply of the city network and the air conditioning system and energy storage. The priority of energy flow is only to passively consider the maximization of the benefits between the energy consumption of the air conditioner and the peak and valley electricity pri...
