Benefits of technology

This technology allows for efficient use of electricity during peak hours when demand exceeds production levels or at other times where there may no more electrical energy being generated compared with what was initially planned. By calculating an optimum operating point (OP) based on realistic operational conditions and utilizing this optimized power flow calculations, it becomes possible to optimize system performance while minimizing costs associated with overfitting certain equipment components such as generators and batteries.

Problems solved by technology

Technological Problem: The technical problem addressed in this patented method for evaluating how well an electrical distribution company's operating efficiency can operate without incurring significant costs due to poorly designed infrastructure or high demand rates during peak hours when there are few resources available.

Abstract

The embodiment of the present invention provides a method and device for calculating an evaluation index of ideal degree of power grid operation economy, which is used for the technical problem that the average power purchase cost index cannot really reflect the dispatching operation business level. The method in the embodiment of the present invention includes: calculating the optimal power flow for each generator set based on the grid operation data to obtain the economically optimal operating position based on the actual operating data of the grid and the grid operation under the condition of the economically optimal operating position. The required power generation curve of each generator set; calculate the first average power purchase cost corresponding to the optimal position of grid operation economy according to the power generation curve and the preset on-grid electricity price, and calculate the first average power purchase cost corresponding to the actual power generation of the unit in actual operation and the preset The set on-grid electricity price calculates the second average power purchase cost corresponding to the actual operation of the power grid; thus, the evaluation index of the ideal degree of economical efficiency of the power grid operation is calculated, and the evaluation index of the ideal degree of economical efficiency of the power grid operation can accurately reflect the dispatching operation business level.
