Abstract

The invention discloses a green scheduling oriented power flow optimization control method. The method comprises the following steps: establishing a power grid simulation data model corresponding to atypical large research mode by using PSD-BPA software, and arranging large generation of new energy in the mode according to the characteristics of the new energy of the power grid; calculating powerflow, searching power transmission blockage and analyzing reasons; for power transmission congestion caused by serious imbalance of power flow distribution, analyzing an optimal compensation scheme for optimizing power flow by utilizing a distributed series compensation device; and determining an operation plan of the distributed series compensation device by combining a day-ahead power generation plan to obtain an optimal operation scheme meeting green scheduling. According to the invention, a section with unbalanced power flow distribution in a new energy concentration area is considered; based on the day-ahead power generation plan, the operation plan of the distributed series compensation equipment is adjusted, influence of commissioning of the distributed series compensation equipment on all aspects of the system is analyzed through simulation, the optimal operation scheme meeting green scheduling is obtained, and a basis is provided for system planning, construction and operation decision making.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a power flow optimization control method oriented to green scheduling. Background technique [0002] The distribution of power flow in the network is naturally distributed according to the line impedance according to Kirchhoff's law. In order to make the power flow flow according to the dispatcher's wishes, it is necessary to have a practical means to control the power flow on each line. In the power grid, due to the fact that the construction of lines and the development of loads are often not synchronized, it is difficult to fully coordinate and match. As a result, some lines are affected by unbalanced load distribution and grid structure, and are in a long-term overload state. light load condition. Unbalanced distribution of power flow reduces the economy and reliability of power grid operation. With the development of new energy, the power grid is in urgent need of an effective...
