An island micro-grid intelligent scheduling system and scheduling method

Abstract

The island microgrid intelligent scheduling system comprises a plurality of user units, a plurality of power generation units, a plurality of combined heat and power generation units and a plurality of boiler units, The user unit comprises electric equipment or electric appliances, a photovoltaic power generation module, a wind power generation module and an electric automobile; The combined heatand power generation unit takes natural gas as a raw material and outputs electric energy to the outside and supplies heat to the outside, and heat supply and power supply of the combined heat and power generation unit are located in a feasible working interval; The boiler unit uses natural gas as a raw material to supply heat to the outside. The invention further provides a scheduling method, theintelligent calculation module selects the user unit, the power generation unit, the combined heat and power generation unit and the boiler unit to purchase, sell and purchase gas strategies throughan intelligent acceleration algorithm, and each unit performs distributed electricity purchase, sell and transaction and heat supply transaction through the block chain system. According to the invention, a price driving and exciting mechanism is set, and the consumption of new energy power generation is promoted. And power generation and power utilization are only transacted in the island, so that the power transmission and heat transmission cost is reduced.

Description

technical field [0001] The invention belongs to the field of power grid dispatching, and in particular relates to an intelligent dispatching system and dispatching method of an island microgrid. 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 the pow...

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.
