The method includes: obtain the parameters and operation condition of each equipment of the power-gas coupling system in a year; determine the different operating states of the system. A programming model of the energy storage device based on reliability constraints is constructed based on the operating state of the system, and benders decomposition algorithm is adopted to calculate the programming model, so that the programming scheme of the energy storage device is obtained. Considering not only the economy but also the reliability of the system, which is more accurate, comprehensive and effective than the previous programming method; the present invention is of great significance to improve the reliability of the electric power system and ensure the safe and reliable operation of the electric power system.

Abstract: The present disclosure provides a device for reducing residual amplitude modulation. The device includes an electro-optic modulation device with three crystals connected in series. The three crystals are the first cubic crystal, an intermediate crystal, and the second cubic crystal respectively. The intermediate crystal is an electro-optic modulating crystal. The intermediate crystal is connected to the high-frequency signal source module. The specification of the intermediate crystal is X mm×Y mm×d mm. The first cubic crystal and the second cubic crystal is connected to both ends of the intermediate crystal in series along the direction of the X axis. The relative dielectric constant of the first cubic crystal and the relative dielectric constant of the second cubic crystal both are equal to the relative dielectric constant of the intermediate crystal. The specification of the first cubic crystal and the specification of the second cubic crystal both are d/2 mm×Y mm×d mm.
