An intelligent grid dispatching system and a dispatching method based on user requirements

Abstract

The invention discloses an intelligent grid dispatching system based on user requirements, which comprises a plurality of user units, a plurality of power generation units, a plurality of cogenerationunits, a plurality of boiler units and a main grid. The subscriber unit comprises an electric equipment or an electric appliance, a photovoltaic power generation module, a wind power generation module and an electric vehicle; Cogeneration unit takes natural gas as raw material, outputs electric energy and provides heat to the outside, and the heating and power supply of Cogeneration unit are in feasible working range. The boiler unit uses natural gas as raw material and provides heat to the outside world. The invention also provides a dispatching method, wherein an intelligent calculation module selects a subscriber unit, a power generation unit, a cogeneration unit, a boiler unit, a purchase and sale electricity and a purchase gas strategy of a main power network through an accelerated intelligent algorithm, and each unit, the main power network, carries out a distributed purchase and sale electricity transaction and a heat supply transaction through a block chain system. The invention sets a price driving mechanism, promotes the consumption of new energy power generation, and effectively improves the reliability of grid operation.

Description

technical field [0001] The invention belongs to the field of power grid dispatching, and in particular relates to a smart power grid dispatching system and dispatching method based on user requirements. Background technique [0002] In recent years, with the rapid development of new energy power generation technology, its application has spread to every household. Although more and more places have begun to deploy distributed new energy power generation systems, due to their close relationship with uncertain factors such as weather and climate, new energy power generation technologies have a large degree of randomness, which in turn causes the impact on the power grid after new energy is connected to the grid. It poses a threat to the reliable operation of the system; due to its large randomness and unstable operation, new energy power generation is not accepted and absorbed by the public, and power abandonment occurs from time to time. In addition, due to the opaqueness of...

Problems solved by technology

Although more and more places have begun to deploy distributed new energy power generation systems, due to their close relationship with uncertain factors such as weather and climate, new energy power generation technologies have a large degree of randomness, which in turn causes the impact on the power grid after new energy is connected to the grid. posed a threat to the reliable operation of the system; due to its large randomness and unstable operation, new energy power generation is not accepted and absorbed by the public, and power abandonment occurs from time to time

In addition, due to the opaqueness of users to the power generation situation, users cannot reasonably arrange power consumption time, resulting in concentrated power consumption time at the load end, which has a greater impact on the power grid

Also there is no technical means in the prior art that can comprehensively solve the above problems

In addition, the traditional power grid adopts a centralized monitoring method, which is not only unfavorable to its reliable operation, but also the user's electricity consumption information needs to be transmitted to the centralized monitoring device, which may easily cause user privacy leakage.

[0003] It can be seen that the existing technology has technical problems such as concentrated electricity consumption by users, leakage of user privacy, and difficulty in accepting and consuming electricity generated by new energy.
