Embodiment Construction

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] In the embodiment of the present invention, the method for quickly smoothing fluctuations of an energy storage system in a multi-energy form of an energy router firstly expresses the operation data collected in real time in the microgrid as:

[0033] Y a,b (t)=Y a,b (t 0 +n×Δt),n=0,1,2,…

[0034] In the formula, Y a,b (t)——The value of the electrical quantity of point b collected at time t a; t 0 —— is the start time of d...

Abstract

The invention discloses a rapid fluctuation stabilizing method for a multi-energy form energy storage system of an energy router. An improved moving average algorithm is utilized to predict a load, an empirical mode decomposition method is utilized to rapidly analyze a power fluctuation quantity, and a control instruction for stabilizing power fluctuation is given to the energy storage system. Simulation analysis through examples shows that power fluctuation of the micro-grid can be effectively stabilized and the electric energy quality of the micro-grid can be obviously improved by rapidly and dynamically controlling charging and discharging of the energy storage system.

Description

technical field [0001] The invention relates to the related technical field of energy routers, in particular to a method for quickly stabilizing fluctuations of an energy storage system in a multi-energy form of an energy router. Background technique [0002] The energy storage module of the energy router mainly includes batteries and supercapacitors. For the energy router energy storage system in the form of heat, electricity and gas, the power quality in the microgrid is very important. The key to improving power quality lies in smoothing the power fluctuations in the power grid. At present, there is a lack of means to quickly smooth and control the power fluctuations of the microgrid in the energy storage system of the multi-energy form energy router. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a method for quickly smoothing fluctuations of an energy router multi-energy energy storage system, so as to solve the problems raised i...
