Benefit Assessment Model and Method for Virtual Control Unit Participation in Frequency Response Control of Provincial Networks

Benefit assessment, as the main means to measure the economy of the project, is the key to ensure that the virtual control unit participates in the frequency response control of the main network to realize the economy. The existing benefit assessment methods and indicator assignment methods are relatively mature, which provide reference for the research of this paper. In this paper, from the perspective of the power grid, in order to ensure the sustainable development of the project, the benefit assessment index system is constructed with economy as the main focus and environmental protection as the supplement; taking into account the degree of influence of the indexes, the hierarchical analysis method and entropy weight method are used for the assignment of the indexes. The example shows that the grid in the big disturbance using the program of transfer instead of cut, this benefit assessment model and method can realize the calculation of the various benefit indicators and the final benefit evaluation, for the virtual control unit to participate in the frequency response control of the main grid to provide a reference for the benefit assessment and measurement.
