Photovoltaic power station power prediction system based on cloud platform

Abstract

The invention discloses a photovoltaic power station power prediction system based on a cloud platform, which comprises a cloud platform, a photovoltaic power station client, a power grid dispatching center and a meteorological data module, wherein the cloud platform is used for calculating a power generation power prediction value of the photovoltaic power station according to the state information of the photovoltaic power station; the photovoltaic power station client is in network connection with the cloud platform and the power grid dispatching center for monitoring and providing the state information of the photovoltaic power station to the cloud platform and adjusting the actual power generation power of the photovoltaic power station according to a power generation power index value of the power grid dispatching center; the power grid dispatching center is in network connection with the cloud platform and the photovoltaic power station client for determining the a power generation power index value of the photovoltaic power station according to the power generation power prediction value of the photovoltaic power station calculated by the cloud platform and sending the power generation power index value to the photovoltaic power station client; and the meteorological data module is in network connection with the cloud platform for providing weather forecast data for the cloud platform. The system of the invention has the advantages of low construction and maintenance cost, convenient maintenance and high prediction precision and the like.

Description

technical field [0001] The invention relates to a photovoltaic power station power prediction system, in particular to a photovoltaic power station power prediction system based on a cloud platform. Background technique [0002] With the trend of energy crisis and environmental pollution intensifying, my country has accelerated the development of renewable energy such as photovoltaics and wind power. The proportion of renewable energy in primary energy has risen from 7.5% in 2005 to 10.3% in 2014. The installed capacity has increased from 166 million tons of standard coal in 2005 to 440 million tons of standard coal. Photovoltaic power generation is developing rapidly. By the end of 2014, the cumulative installed capacity of photovoltaic power generation in the country was 28.05GW, of which 23.38GW were photovoltaic power stations and 4.67GW were distributed. In 2014, the new installed capacity of photovoltaic power generation in China was 10.6GW, of which 8.55GW was distrib...

Problems solved by technology

However, since each photovoltaic power station needs to purchase weather forecast data from the meteorological department, each photovoltaic power station needs to establish a photovoltaic power forecasting background, so the construction and maintenance costs are high and maintenance is difficult; although the forecasting background includes a variety of forecasting Algorithm, but each photovoltaic power station only has the historical data of the power station, so the prediction accuracy is still not high
