Abstract

The invention provides a coordinated operation method of data transmission congestion of multiple photovoltaic power stations, and relates to the field of power grid dispatching. The coordinated operation method of data transmission congestion of multiple photovoltaic power stations comprises the steps of analyzing and calculating parameters which affect data priority classification and then describing the initial dynamic priority of the data of each photovoltaic power station by using a function; building an optimal distribution function by combining with environment parameters of each photovoltaic power station which affect the data transmission and a power generation power coefficient and setting a suitable priority threshold value; comparing the optimal distribution function value of the data transmission with the priority threshold set value to finish the priority classification; and finally realizing priority distribution of the overall data of each photovoltaic power station. According to the coordinated operation method of data transmission congestion of multiple photovoltaic power stations, the data with high priority are processed preferentially, the data congestion problem is solved and the utilization efficiency and the processing speed of the information data of each photovoltaic power station are improved.

Description

technical field [0001] The invention relates to the technical field of grid dispatching, in particular to a coordinated operation method for data transmission congestion of multiple photovoltaic power stations. Background technique [0002] At present, with the gradual heating up of the topic of environmental protection, the development of new energy has become a key project of energy development. Solar energy, as the most representative new energy, has become a strategic focus of energy development. In the safe operation system of the power grid, the photovoltaic power station should be able to transmit remote information to the power system dispatcher, upload the photovoltaic power generation power prediction parameters, power quality information, sunlight intensity, sun incidence angle, and installation of photovoltaic arrays in the photovoltaic power station. Environmental parameters such as angle, conversion efficiency, atmospheric pressure, temperature, and some random...
