Specifically, the energy consumer 111 and the energy producer 112 reach an electric power trading contract by matching the demand for electric power and the quoted price or the available electric power and the quoted price.
The power dispatching platform 115 serves as a delivery and distributor of actual electric power for dispatching the supply of electric power between the energy consumers, the energy producers, and the energy suppliers. After the scheduled energy consumer and the energy producer have reached the electricity trading contract, the electricity scheduling platform 115 performs electricity scheduling according to the electricity trading contract.
The power plant is a conventional power plant and is the main power of power supply, the energy producer may be a new energy producer, such as solar energy, wind energy, etc., and the energy producer further includes an energy storage device. Energy consumers are consumers of electricity, including office buildings, residential quarters, factories, charging piles, and the like. The energy producer can dynamically select different energy suppliers according to market conditions or participate in the virtual power plant system. The energy consumer PU can freely select different energy suppliers/energy producers according to multiple factors such as electricity price, line loss, service and the like, and electric energy transaction is carried out in a mode of signing an intelligent contract.
In the virtual power plant provided by the invention, under the same condition, the power quotation of a new energy producer is lower than that of the power plant, an energy consumer prefers the new energy producer, and in order to stimulate new energy consumption, the traditional power of the power plant is used when the power provided by the new energy producer is not enough to supply the power demand of all energy consumers.
The energy supplier provides energy storage equipment, energy consumers and energy producers within a preset distance range are gathered together according to the positions of the energy consumers and the energy producers to form a trading sub-center, power supply is preferentially scheduled in the trading sub-center through the power scheduling platform, and power trading is generated. Therefore, the loss caused by the long-distance traditional electric power can be avoided, and the electric power utilization efficiency is improved. The method provides relatively objective profits for energy producers, provides relatively high-quality electric energy for energy consumers, and simultaneously consumes redundant energy of a power grid.

In the prior art, power dispatching is generally carried out according to the power requirements of energy consumers, but the application of off-peak power and peak-valley power is not reasonable all the time. According to the invention, the energy storage equipment is used as an energy supplier to participate in a virtual power plant system, the energy storage equipment stores energy by using off-peak electricity and achieves an electric power transaction intelligent contract for supplying power with an energy consumer at a peak-valley electricity stage; and the power dispatching platform dispatches power according to the distance and the loss. Thereby further improving the rationality and economy of the power supply.
And the power dispatching platform dispatches power supply according to the power consumption prediction of each energy consumer and generates power transaction.

As a further improvement scheme of the invention, the electric power trading platform inputs the intelligent contract by taking the platform area as a boundary condition, and automatically judges whether the electric power trading can be carried out or not when the boundary condition is triggered. Furthermore, in a specific area (such as a united platform area), automatic checking of scheduling is realized through an intelligent contract, transactions are automatically matched, and a transaction clearing mode is determined. Therefore, according to the scheme provided by the invention, the boundary checking condition of power dispatching in one (or a plurality of specific) transformer areas can be simplified, and the method is more suitable for automatic checking of intelligent contracts, matching transactions and executing inaccessible clearing modes (and prices).
The power distribution area refers to a power supply range or area of one transformer in the power system. The transaction clearing mode can be unified clearing or scattered clearing.
Specifically, for an intelligent contract, the platform area is taken as a boundary checking condition, a complex boundary checking condition is not needed, and the scheduled boundary checking condition is simplified. For example: at the same time, different energy consumers are in different districts, so that different clearing modes can be adopted, and different transaction prices can be obtained.
Based on the virtual power plant system and the block chain network structure, the invention also provides a virtual power plant operation method, which specifically comprises the following steps:
