Embodiment 1

[0060] Like the power system described above, this embodiment differs from it in that figure 2 As shown in the structure diagram of the power collection device of the present invention, the power collection device 1 includes an active power meter 11, a reactive power meter 12, a power microprocessor 13 and a power signal transmitter 14. The active power meter 11 measures the active power of the user or load ; The reactive power meter 12 measures the reactive power of the user or load; the power microprocessor 13 compensates for the error between the active power and the reactive power, and calculates the active power and the reactive power; the power signal transmitter 14 combines the active power with The reactive power is transmitted to the background processing device 4.

[0061] Among them, electrical energy can be converted into various energy. For example, it is converted into heat energy by an electric furnace, mechanical energy by a motor, and light energy by an electric...

Embodiment 2

[0064] Like the power system described above, this embodiment differs from it in that image 3 As shown in the structure diagram of the line loss collection device of the present invention, the line loss collection device 2 includes a current collector 21, a line loss microprocessor 22 and a line loss signal transmitter 23; the current collector 21 is installed on the power transmission and distribution line to collect and transmit The current value on the distribution line is transmitted to the line loss microprocessor 22; the line loss microprocessor 22 compensates for the error of the current value and calculates the line loss power; the line loss signal transmitter 23 transmits the line loss power to the background processing Device 4.

[0065] Error compensation can greatly reduce or eliminate the error of the current collector due to mechanical reasons or changes in current temperature, and improve the accuracy of measurement.

Embodiment 3

[0067] As with the power system described above, this embodiment is different from it in that the formula for calculating the amount of electricity to be determined by the background processing device 4 is:

[0068]

[0069] Among them, the calculation formula of X is:

[0070] X = ( - 1 ) n + 1 + 1 2 x n + 1 2 + ( - 1 ) n + 1 2 x n 2 + x n + 2 2 2

[0071] In the above formula, Q is the required electric quantity to be determined, i is the serial number of electric quantity data of the same electric quantity calculated in different ways, x i Is the electric quantity data counted for the same electric quantity for the i time, n is the total number of electric quantity data counted for the same electric quantity, X is the central value, and M is the maximum value of the distance between the electric quantity data to be retained and the central value, For the same power Th...

Abstract

The invention discloses an electric power system and an electric power market participant risk assessment system. The electric power system comprises an electricity quantity acquisition device, a line loss acquisition device, an input controller and a background processing device, wherein the electricity quantity acquisition device acquires the electricity consumption amount of a user and the transmission electricity quantity of each level of power grid; the line loss acquisition device acquires a line loss electricity quantity; the input controller inputs the name of an electricity quantity to be determined; and the background processing device calculates the electricity quantity to be determined. The electric power market participant risk assessment system also comprises a market acquisition device, a model establishment unit, an index determination unit, an index screening unit and a pressure test unit, wherein the market acquisition device acquires market information data; the model establishment unit establishes a behavior model of the electric power market participant; the index determination unit determines a pressure-bearing index and a risk index; the index screening unit screens a key risk index which has a high influence degree on a pressure-bearing index variable; and the pressure test unit evaluates the risk to which the participant faces under an extreme condition. Therefore, through the flexible acquisition of the electricity quantity and the pressure test, the risk to which the electric power market participant faces under the extreme condition can be effectively evaluated.

Description

Technical field [0001] The invention relates to the field of power and power market risk assessment, in particular to a power system and power market participant risk assessment system. Background technique [0002] The concept of stress test (StressTest) was first proposed by IOSCO (International Organization of Securities Regulators) in 1995. It assumes that the market is in the most unfavorable situation (such as a sudden rise in interest rates or a sudden plunge in the stock market). The effect of the impact. IOSCO made a further supplement in 1999: stress testing is to identify and quantify the possible risks of extreme methods faced by the asset portfolio. [0003] In 2000, BCGFS (Bank for International Settlements, Basel Bank Global Financial System Committee) defined stress testing as a model for financial institutions to measure potential but plausible abnormal losses. And in 2009, the supplementary stress test is a tool to assess the financial loss faced by banks in ser...
