Embodiment Construction

[0113] The present invention will be further described below in conjunction with the accompanying drawings.

[0114] refer to Figure 1 to Figure 10 , an automatic demand response method for an energy storage system based on a non-cooperative game, the method includes the following steps:

[0115] S1: Establish game participants as owners of all vehicles and batteries in the energy local area network system, denoted as v i , i∈Γ, Γ=(1,2,...,N), Γ refers to the set of all game participants, and N is the number of game participants;

[0116] S2: Discretize the continuous time, the optimal time period is 24h, which is divided into K time periods equally, for any kth time period, there is k∈{1,2,...,K}, and the duration of the kth time period is Δt, the present invention uses 0.5h to obtain the status information of the energy storage system connected to the energy local area network, and establishes the PEV charging and discharging power model and the ESS energy storage model; ...

Abstract

A non-cooperative game-based automatic demand response method for energy storage systems in energy local area networks, obtaining the state information of energy storage systems connected to energy local area networks, establishing a charging and discharging model of energy storage systems, and constructing utility functions of game participants to calculate their participation The cost after the game; each game participant independently formulates strategies and conducts interactive games to solve their own cost minimization optimization strategies, so as to achieve the optimal target state of all participants; finally, the non-cooperative game mechanism is used to simulate the power transaction process, which proves that effectiveness of the proposed method. The invention establishes a non-cooperative game model of the energy storage system aiming at the energy local area network, aiming at minimizing the cost of individual participants, improving the consumption level of renewable energy, and realizing the independent supply and demand balance and automatic demand response of the system.

Description

technical field [0001] The invention relates to an automatic demand response method for an energy local area network energy storage system based on a non-cooperative game. Background technique [0002] In order to cope with the multi-state status quo of the depletion of primary energy, the sharp increase in energy demand, and the imperative of environmental protection, a new round of energy transformation centered on electric energy and characterized by large-scale development and utilization of new energy is booming. Among them, the Energy Internet, which deeply combines new energy technology and information technology, has received extensive attention. Renewable Energy Sources (Renewable Energy Sources, RES), Energy Storage System (Energy Storage System, ESS) and electric vehicles ( Plug-in Electric Vehicle (PEV), etc. have played an important role in the future new energy architecture. [0003] Energy Local Network (ELN) is a typical sub-network of the Energy Internet, w...
