Problems solved by technology

The coordination center has the user's device information and transaction records. Once the information is leaked, it will cause serious consequences; and each subject cannot obtain the transaction information of other subjects, but only has its own data information, so it is difficult to establish a mutual trust trading market
In addition, the establishment and operation of the energy coordination center requires investment costs and employment costs, resulting in high operating costs, and unreasonable trading strategies will also affect the benefits of each entity

Embodiment

[0037] Such as figure 1 As shown, each microgrid in the multi-microgrid system is regarded as an equivalent energy management entity, and each microgrid can propose an energy transaction plan or evaluate the plan, thereby constructing a decentralized decision-making and energy management system without a central management unit. Distributed energy management architecture. The multi-micro-network transaction mechanism and process under the co-governance mode are designed: the multi-micro-grid system implements the micro-network that proposes the corresponding plan will get a certain reward, and each micro-network needs to propose a coordination and optimization plan according to the characteristics of the multi-micro-grid system in order to obtain the corresponding reward. Compete, score and evaluate the remaining micro-grids, and decide on an implementation plan, so as to realize multi-party governance and decision-making. In the multi-microgrid system, each microgrid plays a...

Abstract

The invention discloses a multi-party co-governance decision-making method for multi-microgrid coordinated transaction, and relates to the technical field of multi-microgrid energy coordinated transaction, and the method comprises the steps: obtaining an alternative energy transaction scheme of a multi-microgrid system, and carrying out the preliminary evaluation of the alternative energy transaction scheme of the multi-microgrid system, judging whether the alternative energy transaction scheme of the multi-microgrid system reaches a set score or not, and if not, obtaining the alternative energy transaction scheme of the multi-microgrid system again; if yes, the alternative energy transaction scheme of the multi-microgrid system is calculated, a calculation result is fed back to each sub-microgrid, each sub-microgrid scores the calculation result according to multiple scoring indexes, and the multiple scoring indexes comprise an economy scoring index, a fairness scoring index, an environmental protection scoring index and a safety scoring index; and summarizing the scoring results of the sub micro-grids, and selecting the highest scoring result as a multi-dimensional network system energy transaction scheme.

Description

technical field [0001] The invention relates to the technical field of multi-microgrid energy coordinated transactions, in particular to a multi-party co-governance decision-making method for multi-microgrid coordinated transactions. Background technique [0002] In recent years, with the rapid development of distributed power generation and the continuous deepening of energy market reforms, distributed energy trading methods have received widespread attention. The microgrid has the characteristics of high flexibility and strong autonomy, and is the main application scenario for distributed energy to participate in market transactions. Multiple microgrids in the same area are connected to the distribution network to form a multi-microgrid system. Due to the differences in load characteristics and energy output of different microgrids, energy trading between microgrids can not only reduce the dependence of multi-microgrid systems on distribution networks, but also promote th...
