摘要

过去相关文献主要集中考虑虚拟电厂的经济运行。弃风弃光现象在实际操作中不可避免，不利于新能源的消纳。配电网作为传统交易模式下的运营主体，兼顾电网调度和经济交易管理的双重角色，为减少重要商业信息的传递并促进新能源消纳，提出了一种结合目标级联法求解的分布式交易模型。首先，建立差异性价格模型并据此建立集中交易模型，利用拉格朗日分解法将配电网运营商与各虚拟电厂运营商之间的耦合变量约束引入集中交易模型，建立分布式交易模型，并采用目标级联法进行求解。在减少弃风和弃光现象的同时，减少信息传递并提高安全性。最后，在69节点测试系统中验证了提出方法的有效性和实用性。

Abstract

In the past

relevant studies mainly focused on the economy of virtual power plant operation. It is inevitable to abandon wind and light in actual operation

which is not conducive to the consumption of new energy. At the same time

under the traditional transaction mode

the distribution network

as the main opera-tor

takes the dual roles of power grid dispatching and economic transaction management into account. However

virtual power plants are mostly independent operators

and transaction information belongs to important commercial privacy. The way of distribution network coordination is not in line with the reality of the market. Therefore

a distributed transaction model

which is solved by target cascade method is proposed. While promoting the consumption of new energy in virtual power plants

information transmission to improve safety is reduced. Firstly

based on the established differential price model

the centralized transaction model is established.The coupling variable constraints between distribution network operators and virtual power plant operators are introduced into the centralized transaction model by Lagrange decomposition method

the distributed transaction model is established

and the analysis target cascade method is used to solve it. Finally

an example is given to verify the effectiveness and practicability of the model.
