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

The invention discloses an energy storage system automatic demand response method based on a non-cooperative game, and the method comprises the steps: obtaining the state information of an energy storage system accessed to an energy local area network, and building an energy storage system charging and discharging model; Constructing a utility function of a game participant to calculate the cost of the game participant after the game participant participates in the game; enabling Each game participant independently to formulate a strategy and perform an interactive game, and solve the respective cost minimization optimization strategy, thereby achieving the optimal target state of all the participants; And finally, simulating a power transaction process by utilizing a non-cooperative gamemechanism, and proving the effectiveness of the provided method. The non-cooperative game model of the energy storage system is established for the energy local area network, the consumption level ofrenewable energy sources is improved while the cost of individual participants is pursued to be minimized, and autonomous supply and demand balance and automatic demand response of the system are achieved.

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...
