Wind power grid connection indicators refer to the ability and conditions of wind farms to connect to the grid, which usually include the following aspects:
1. Grid interface capacity: refers to the interface capacity between wind farms and the grid. That is the ability of wind farms to deliver electricity to the grid. The greater the grid interface capacity, the greater the power generation capacity of the wind farm.
2. Power grid stability: refers to the stability and reliability of the power grid, including voltage, frequency, power factor, etc. When a wind farm is connected to the power grid, it needs to meet the stability requirements of the power grid to ensure the normal operation of the power grid.
Technical regulations for connecting wind power to the power grid
Improve system flexibility.
The connection of large-scale wind power, photovoltaic power generation and other new energy power generation to the power grid has increased the requirements for system flexibility. There is an urgent need to explore new key energy storage technologies to enrich peak and valley time-of-use electricity prices, Seasonal electricity prices and differentiated electricity price systems.
Photovoltaic generation system, referred to as photovoltaic, refers to a power generation system that uses the photovoltaic effect of photovoltaic cells to directly convert solar radiation energy into electrical energy.
Legal analysis: "Technical Regulations for the Connection of Wind Farms to Electric Power Systems" (GB/T 19963-2011 replaces GB/Z 19963-2005) by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China and China The National Standardization Administration Committee issued it on December 30, 2011 and came into effect on June 1, 2012. This standard specifies the technical requirements for wind farms to be connected to the power system.
"Technical Regulations for Wind Farms Connected to Electric Power Systems Part 1: Onshore Wind Power" (GB/T 19963.1-2021 replaces GB/T 19963-2011) by the State Administration for Market Regulation and the National Standardization Administration Released on August 20, 2021, implemented on March 1, 2022, and drafted in accordance with the provisions of GB/T1.1-2020 "Standardization Work Guidelines Part 1: Structure and Drafting Rules of Standardization Documents". This document focuses on the technical requirements for onshore wind power grid connection, and clarifies the basic technical requirements that power grid companies and power generation companies must meet during the onshore wind power grid connection operation1 to ensure the safety and stability of the power grid and onshore wind farms. run.
Legal basis: Article 1 of the "Technical Regulations for Wind Farms Connected to Power Systems" This standard specifies the technical requirements for wind farms connected to power systems. This standard applies to newly built or expanded wind farms connected to the power system through voltage lines of 110 (66) kV and above. For wind farms connected to the power system through other voltage levels, reference can be made to the implementation.
