Power grid overall balance analysis system based on data lake

Abstract

The invention relates to the technical field of power distribution systems, and concretely relates to a power grid overall balance analysis system based on a data lake. A big data analysis algorithm service is utilized to establish an association relationship between watershed water regimen (watershed incoming water, reservoir energy storage ratio and the like) and the hydroelectric power generation capacity of the whole network, and then the hydroelectric adjustable capacity of the day is estimated according to recent water regimen and actual hydroelectric power generation conditions. And a thermal power starting condition, a trans-provincial and trans-regional tie line plan, a national dispatching power plant plan and a new energy real-time power generation level are further added to obtain the maximum and minimum adjustable capability of each provincial network on the current day. And on the other hand, according to the current electrical load trend, combining yesterday data comparison, and calculating the load in peak and valley periods within the day in a rolling manner. The system aims at achieving intelligent analysis of power grid balance and improving the intelligent operation evaluation level of an existing dispatching control system.

Description

technical field [0001] The invention relates to the technical field of power distribution systems, in particular to an overall balance analysis system of a power grid based on a data lake. Background technique [0002] With the increasingly complex characteristics of the power grid and the gradual deepening of power market-oriented reforms, it is difficult to control the dispatching operation of the power grid, the scope of abnormal faults is wide, and the requirements for clean energy consumption are high. It is necessary for the dispatcher to accurately evaluate the real-time status of the main grid and the safe operation margin. , to ensure the safe and stable operation of the power grid while improving the level of economic operation. [0003] At present, the real-time monitoring and early warning applications and safety checking applications deployed in the power grid dispatching control system provide dispatchers with multiple research and analysis tools, but the funct...

Problems solved by technology

[0003] At present, the real-time monitoring and early warning applications and safety checking applications deployed in the power grid dispatching control system provide dispatchers with multiple research and analysis tools, but the functions or requirements of each application are relatively single and independent, and they do not have the ability to integrate the application information of each function , the ability to independently study and judge the overall operating status and risks of the power grid for the core business of dispatching operation relies heavily on the experience of dispatchers
