Regional energy internet coordinative optimization operation method

Abstract

The invention discloses a regional energy internet coordinative optimization operation method. The regional energy internet coordinative optimization operation method is oriented to a regional energy internet with a micro energy grid as a basic energy supply unit, and provides a coordinative optimization operation method for guiding electric energy interaction between different micro energy grids based on regional power market pricing; starting from the benefit of the micro-energy network, the regional energy internet coordinative optimization operation method establishes a micro-energy network day-ahead autonomous optimization scheduling model with supply and demand two-side collaboration; the regional energy internet coordinative optimization operation method introduces an unbalanced cobweb model to establish a pricing transaction model of the regional power market and form a double-layer interaction structure of market price adjustment and micro-energy grid autonomous optimization, and after double-layer interaction is in a stable state, the regional power market distributes actual transaction electric quantity to an excessive supply or excessive demand side; and each micro-energy grid performs final independent autonomous optimization according to a distribution result. The regional energy internet coordinative optimization operation method can realize stable transaction in an unbalanced state, so that the operation performances such as respective economy, environmental protection and the like between the micro-energy networks are improved through efficient electric energy 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...

Problems solved by technology

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
