A Correction Method for Baseline Value of Network Loss During Assessment Period

Abstract

The invention discloses a method for correcting a reference value of transmission loss in an assessment period. The method comprises the steps of 1, defining the time length of one assessment period; 2, finding out the transmission loss Lossa of the system after a power grid coordination control strategy is implemented; 3, calculating the power consumption li of the system within an ith reference period with the time length corresponding to that of the assessment period; 4, calculating an average value lavg of the power consumption in n reference periods; 5, calculating an average value Lossavg of the transmission losses in the n reference periods; 6, calculating the transmission loss Lossb of the system before the power grid coordination control strategy is implemented; and 7, calculating the transmission loss reduction rate according to the transmission loss Lossa and the transmission loss Lossb. Under the condition that the transmission loss of the system after the power grid coordination control strategy is implemented and a power grid load curve of the system within a fixed assessment period before the power grid coordination control strategy is implemented are known, the transmission loss of the system before the strategy is implemented is solved, and the transmission loss reduction rate is calculated, so that energy-saving effects of implementing the power grid coordination control strategy of the system are evaluated according to the transmission loss reduction rate.

Description

technical field [0001] The invention relates to a correction method for a network loss reference value during an assessment period, and belongs to the technical field of evaluating the implementation effect of a coordinated control strategy of a power grid. Background technique [0002] Energy is an important material basis for the survival and development of human society, and it is also the main source of power for the progress of industrial civilization. After entering the 21st century, the trend of energy shortage on a global scale has become more and more obvious. Based on the combination of developing new energy and new technology, establishing a new type of clean, safe and sustainable energy system has become the current energy development trend. In order to effectively promote the transformation of energy production and consumption patterns, the Chinese government has vigorously promoted the development of new energy sources such as wind power, photovoltaic power gen...

Problems solved by technology

However, with the rapid development of my country's new energy industry, large-scale new energy bases are facing a series of technical difficulties such as limited power grid consumption, narrow delivery channels, and blocked delivery capabilities.

[0003] Under the constraints of a series of bottlenecks such as the sharp increase in power grid transmission loss, insufficient peak-shaving capacity of conventional power sources, and obstruction of new energy delivery, the operation mode of network-source coordination and source-source coordination alone cannot meet the needs of the development of large-scale new energy bases. There is an urgent need to open up new ideas, discover new models, and seek new methods to solve the two-way contradiction between the development of new energy bases and power grid energy conservation and loss reduction
