The unreasonable energy consumption not only makes Chinese modern energy industrial system difficult to be built, but also has a bad influence on Chinese economy in health and sustainable development. In this paper, the main performance and reasons about the structure of Chinese energy consumption are analyzed and some price regulation mechanisms which are all for optimizing energy consumption structure...
Static security region (SSR) plays a crucially important role in power system monitoring and operation. Boundaries of SSR are usually obtained through continuation power flow (CPF) calculation. Considering the effects of generation regulation, this paper improves the CPF for boundary computation of SSR in two aspects: 1) a general method of handling the effects of active power and reactive power limits...
The visualization techniques improve the power grid operation, and help the operators grasp the overall situation of the system profile. Voltage-contour is one of the advance techniques to show and help to quickly figure out the voltage violations. Nowadays, the major difficulty of voltage-contour visualization technique applied in the power grid is the image-generation-speed. The speed can't catch...
Short-term load forecasting is the basis for the safe operation of power systems. The accuracy of forecasting will have a direct impact on the load distribution of the entire power grid. There are many factors affecting the load, while the method based on similar historical days' data can fully consider these factors. It forecasts load by selecting similar historical days' data and then obtaining...
