Abstract

The present invention provides a photovoltaic power station power testing method based on simulation scheduling. The method comprises the steps of (1) carrying out communication connection on a simulation scheduling system and photovoltaic power plants AVC and AGC, (2) simulating grid scheduling in the simulation scheduling system, issuing active and reactive power values to all photovoltaic power plants, and recording instruction values and issuing times, (3) calculating active and reactive power frequency response time and control precision through the all active and reactive powers of all photovoltaic power plants monitored by a power analysis instrument, and calculating AVC and AGC system response times. The method is used for testing the active / reactive performance of the photovoltaic power plants, a scheduling link is included, and the testing precision is improved.

Description

technical field [0001] The invention relates to a power testing method, in particular to a photovoltaic power station power testing method based on simulation scheduling. Background technique [0002] With the continuous increase of the installed capacity of photovoltaic power plants, its impact on the power grid is increasing. In order to ensure the safe operation of the power grid, the national standard GB / T19964-2012 "Technical Regulations for Connecting Photovoltaic Power Stations to Power Systems" clearly stipulates the active / reactive power response performance of photovoltaic power stations. At the same time, the power system dispatching department also has clear requirements on the active / reactive power response capability of photovoltaic power plants. It is clear that the power station needs to be equipped with AGC and AVC systems to ensure the ability of the power station to participate in grid dispatching. At the same time, with the development of dispatching syst...
