Photovoltaic power generation predicting system and predicting method

Abstract

The invention discloses a photovoltaic power generation predicting system, which comprises a predicting module started at a fixed time, a manually started predicting module, a predicting statistics calculating module, a device managing module, and a weather detecting module wherein the predicting module started at a fixed time is connected with the predicting statistics calculating module and is provided therein with the preset starting time; and when the starting time is due, the predicting statistics calculating module is triggered to make statistics of the device data and weather data. The weather detecting module is connected with an international meteorological station server to access the real time weather conditions in real time and to transmit the accessed data to the predicting statistics calculating module. The device managing module is connected with the server of the photovoltaic power generation equipment, obtains the number, the longitude and latitude, the placing angle of the photovoltaic power generation equipment and the type data of the photovoltaic materials, and at the same time, transmits the data to the predicting statistics calculating module. The predicting statistics calculating module integrates the gathered weather data and the device data and obtains the predicted power generation amount through the calculation of a mathematic model.

Description

technical field [0001] The invention relates to the field of photovoltaic power generation, in particular to a photovoltaic power generation forecasting system and a forecasting method. Background technique [0002] Traditional fossil energy is decreasing day by day, environmental pollution is increasing day by day, and severe weather conditions have become a global issue. The development and application of renewable clean energy is gradually occupying the commanding heights of energy strategies of countries around the world. With its inexhaustible, widely distributed, safe and clean characteristics, solar energy has become an ideal new generation of renewable energy. [0003] Photovoltaic power generation is divided into two forms: off-grid and grid-connected. With the maturity and development of photovoltaic grid-connected technology, solar photovoltaic grid-connected power generation has become the mainstream trend. Due to the rapid increase in the capacity of large-scal...
