A coordinated and optimized operation method for regional energy internet

Abstract

The invention discloses a method for coordinating and optimizing the operation of the regional energy Internet. The method is oriented to the regional energy Internet with the micro-energy network as the basic energy supply unit, and proposes a method based on regional power market pricing to guide different micro-energy networks to perform electric energy interaction. Coordinate and optimize the operation method; start from the interests of the micro-energy network, establish a self-governing optimization scheduling model of the micro-energy network that coordinates both sides of the supply and demand; introduce an unbalanced spider web model to establish a pricing transaction model for the regional power market, and form a market price adjustment and micro-energy network Self-optimized double-layer interactive structure. After the double-layer interaction reaches a stable state, the regional power market will distribute the actual transaction power to the excessive supply or excessive demand side, and each micro-energy network will carry out the final independent autonomous optimization according to the distribution results; the present invention forms The coordinated and optimized operation method can realize stable transactions under non-equilibrium conditions, so that the micro-energy grids can improve their economic and environmental performance through efficient power interaction.

Description

technical field [0001] The present invention relates to the field of electrical information technology, in particular to a method for coordinated and optimized operation of regional energy internet. Background technique [0002] As the energy and environmental crisis continues to deepen, the energy industry has proposed the concept of "Energy Internet (Energy Internet, EI)", which requires breaking down the barriers in various energy fields, based on advanced Internet communication technology, using various energy conversion equipment and energy storage The equipment performs energy coupling operation in the fields of electricity, gas, heat, cold, and transportation, so that clean and renewable energy can be fully absorbed, and the utilization efficiency of fossil energy can be improved through cascade utilization. During the construction and development of EI, a layered structure system of "Backbone Energy Internet-Regional Energy Internet (REI)" will be gradually formed, a...

With the increase of MEG, this method will not only put pressure on the operation of the power grid company, but also cause poor economic performance of MEG operation

In addition, some studies have proposed a coordinated optimization operation method under the coexistence of multiple micro-energy grids, but the transaction energy price between MEG and distribution network or MEG is still regarded as a fixed value, and only the interaction energy Coordination, which may prevent certain MEGs from gaining benefits in coordination and optimization, will not be applicable to the situation in which MEGs are subordinate to different stakeholders in the process of power market reform; or coordination is only carried out by pricing within a day Analysis of optimal operation, lack of study of the entire scheduling cycle ahead of the day
