Real-time dispatching method for improving clean energy absorption capacity of power grid

Abstract

The invention discloses a real-time dispatching method for improving the clean energy absorption capacity of a power grid. The method comprises the steps that the phenomena that clean energy is sent out with heavy load from a section and the output of the clean energy is limited are discovered; the output potential of a transmission channel is excavated; a clean energy power generation policy is optimized, and the operation mode of the power grid is adjusted; and real-time power generation dispatching is carried out according to an integrated and adjusted power generation dispatching program.According to the invention, the method starts from the dispatching reality, designs a set of application processes according to a standardized process system, and is targeted and practical; the searchefficiency is high and the check result is reliable when the power limit of the power grid clean energy sent out of the section is acquired; the timeliness requirement of real-time dispatching can besatisfied; and the method analyzes the power grid from different perspectives, is applicable to different power grid characteristics and different absorption needs, can be applied alone, can be compositely applied through an integration process, and has the advantages of flexibility and high efficiency.

Description

technical field [0001] The invention specifically relates to a real-time scheduling method for improving clean energy consumption capacity of a power grid. Background technique [0002] With the development of national economy and technology and the improvement of people's living standards, electric energy has become an indispensable secondary energy source in people's daily production and life, bringing endless convenience to people's production and life. However, with the improvement of people's living standards, the problem of environmental pollution is becoming more and more serious. [0003] Clean energy, also known as green energy, refers to energy that does not emit pollutants and can be directly used for production and life, mainly including solar energy, wind energy, water energy, geothermal energy, tidal energy, and biomass energy. In my country, water energy has been developed and utilized on a large scale, and wind power and photovoltaic power generation have al...

Problems solved by technology

However, due to the relatively stable periodic characteristics and uninterruptible requirements of the grid load, the planning attribute of the real-time power generation dispatch of the grid is still strong, and it is still difficult to adapt to the large-scale clean energy grid power generation.

[0005] At present, due to the limitations of transmission channels, grid structure, and power receiving capacity of the receiving end grid, the demand for sending clean energy from the domestic grid cannot be fully met. Prominent contradictions in multiple provinces

The essence of the problem of clean energy consumption lies in the structural and phased mismatch between power grid and power supply construction. The key is that the demand for power transmission exceeds the safety and stability limit of the grid channel; the contradiction of clean energy consumption can be alleviated to a certain extent through optimal scheduling, but at present There is no practical method for real-time dispatching of power grids specifically for clean energy consumption services
