Introduction

The security of power grid is related to the national strategic security, and the quality of supporting service provided by photovoltaic power stations to the power grid directly affects the safe operation of the power grid: Establish the evaluation and certification mechanism for the hardware facilities, grid-connected performance and operation and maintenance management capabilities of photovoltaic power stations is to control and improve the grid-connected services of photovoltaic power stations effective means of capacity: With the proposal of the "double carbon" goal and the goal of building a new power system with new energy as the main body, photovoltaic power generation has the proportion in the network will increase rapidly, and gradually become the main power supply: The stability of the power grid will face a new situation, and the service certification of photovoltaic power stations will development is particularly urgent:

Power station facilities are the hardware that must be configured for photovoltaic power stations and meet the requirements of relevant standards, and are the basis for realizing various functions of the power station:

The completeness and performance quality of photovoltaic power plants directly affect the grid-connected performance of photovoltaic power stations: Grid-connected requirements are the basic requirements for photovoltaic power stations to be connected to the grid:

The grid-connected performance of photovoltaic power stations directly affects the safe and stable operation of the grid: The excellent power prediction performance of photovoltaic power stations will improve photovoltaic consumption, Optimizing power grid dispatching operation; excellent grid-connected tolerance and support performance will improve the coordination, safety, economy and efficiency of the source network; high level the operation and maintenance management of the power station will improve the operation safety of the power station, prolong the life of the power station, and benefit the reliable operation of the power grid:
