Embodiment
[0022] Such as figure 1 , 2 The operation method of a high-efficiency and energy-saving power network includes a power network control center, a power generation side, a grid power consumption side and a high-load power consumption side, and the rated output power of the power generation side is constant or basically constant; the operation method includes the following step:
[0023] 1) The power network control center calculates the disposable electric power for users in high energy-consuming industries based on the load forecast value of the power grid and the rated output power of the power generation side ( figure 1 Middle Line 4); the power grid predicts the load according to the traditional power grid ( figure 1 Middle Line 1) to remove the power load of traditional high energy-consuming industries, that is, to obtain new grid-side user loads ( figure 1 Middle Line 3); thermal power plants and nuclear power plants operate according to the optimal output load, some sm...

The invention relates to a method for operating a power grid with high efficiency and energy saving, belonging to the field of a power control technology. The method comprises the following steps: a control center of the power grid, according to a load prediction value in the power grid and a rated output power at a power generating side of the power grid, calculates a disposable electrical energy power for a high energy-consuming industry user in the power grid, wherein the disposable electrical energy power is a difference between the rated output power and the load prediction value; the high energy-consuming industry user carries out an electricity utilization work according to the disposable electrical energy power. The method changes the high energy-consuming industry into a high-efficiency industry, reduces the operating cost of the enterprises, realizes the stable operation of a power grid, improves the utilization rate of the power grid, guarantees the high load operation of a thermal power and a nuclear power and avoids increasing the enterprise production cost of the thermal power enterprises and the nuclear power enterprises due to load regulation; meanwhile, the method ensures that the renewable energy power generation can be merged into the power grid completely for utilization.
Description
technical field [0001] The invention relates to an operation method of a power network, belonging to the technical field of power control. Background technique [0002] Since the reform and opening up, China's economy has shown a rapid growth momentum. From 1978 to 2004, the annual growth rate of China's per capita GDP was 8.16%, which has always been at the forefront of the world's GDP growth and has achieved world-renowned achievements. The rapid economic growth at this stage and the continuous optimization and evolution of the industrial structure played an important role. [0003] The secondary industry is a pillar industry of our country. However, under the guidance of China's economic and industrial structure transformation policy, the industry as a pillar industry of our country is also facing the challenge of transformation. High energy-consuming industries are under the influence of regulatory policies such as resolving the contradiction of overcapacity. , the prop...
