Embodiment Construction

[0098] The present invention will be further described below in conjunction with the accompanying drawings.

[0099] refer to Figure 1 to Figure 6 , an automatic demand response method for energy storage systems based on blockchain technology, the method includes the following steps:

[0100]S1: Discretize the continuous time, the optimization period is 24h, and it is equally divided into K periods. For any kth period, there is k∈{1,2,...,K}, and the duration of the kth period is Δt, the present invention uses 0.5h to obtain the state 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;

[0101] S2: Establish a comprehensive evaluation system for electric vehicle (EV) schedulable ability (SA), the evaluation indicators are selected as the loss degree of EV power battery, EV user credit and EV reverse power supply capability, and adopt fuzzy control ...

Abstract

The invention provides an energy source local area network energy storage system automatic demand response method based on a block chain technology. The method comprises the following steps of obtaining state information of the energy storage system connected into an energy source local area network; building an energy storage system charging and discharging model; building an electric automobileschedulable capability comprehensive evaluation system; using a real-time electricity price mechanism; setting charging and discharging electricity price orienting electric automobile users; finally developing a decentered automatic demand response criterion on the basis of the block chain technology; building an intelligent contract between two trading parties. By aiming at the energy source local area networks comprising an electric automobile cluster, a wind light power generation system and an energy storage battery, a distributive node network for charging and discharging by the user is built by the invention for pursuing point-to-point direct trading of mass users; reasonable configuration of inside resources of the system is realized; the autonomous supply and demand balance state is 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 block chain technology. Background technique [0002] At present, the world is facing the plight of depletion of primary energy and increasingly severe environmental problems, while energy demand continues to grow. A new round of energy transformation centered on electricity and characterized by large-scale development and utilization of new energy is booming. Energy local area network The concept came into being. The energy local area network is defined as a complex multi-network flow system formed by taking the power system as the core, based on the Internet and other cutting-edge information technologies, using renewable energy as the main primary energy, and tightly coupled with other systems such as natural gas networks and transportation networks. [0003] As a typical subnet of the Energy Internet, Energy Local Network (E...
