Distributed power supply has become an important source of electricity for Zhejiang Power Grid to build a green power grid

The reporter learned from the Zhejiang Electric Power Company that distributed power, including wind power, photovoltaic power generation, and small hydropower, is becoming an important source of energy for Zhejiang power grids.

During the “Eleventh Five-Year Plan” period, the installed capacity of wind power in Zhejiang increased by an average of 49.6%. By the end of 2011, the installed capacity of grid-connected wind power in the province had reached 320,000 kilowatts, an increase of nearly 10 times over 2000. From 2009 to 2011, Zhejiang Electric Power Company received a total of 99 power grid photovoltaic projects with a capacity of approximately 195,000 kVA. The distributed, miniaturized and clean features of these distributed power sources have promoted the optimization of energy structure and energy conservation and emissions reduction in Zhejiang.

Distributed power is a form of power production that is comparable to centralized power generation. In recent years, under the guidance of the State Grid Corporation of China's green development strategy, Zhejiang Electric Power Co., Ltd. has actively created conditions for the development of distributed power sources and strived to promote the development of the green power grid. In March 2010, the company built a distributed power supply and microgrid technology research laboratory, and was the first in China to implement an integrated microgrid system that includes a variety of distributed power supplies and energy storage systems, and enables flexible switching between grid-connected and standalone modes. In May 2012, the company undertook the national 863 project "Research and Development of Key Technologies for Microgrid with Distributed Power Supply" to build a microgrid demonstration project.

Zhejiang Electric Power Company also advanced technology research and provided technical support for photovoltaic power generation to access the power grid. At present, the province has formulated and issued the Interim Measures for the Administration of the Access to Power Grids of Zhejiang Solar Power Projects, the Application Rules for the Application of Photovoltaic Power Grids to the Power Grids of the Zhejiang Electric Power Company (Trial), and the Regulations on the Grid Dispatching of Large and Medium-sized Photovoltaic Power Plants of the Zhejiang Electric Power Company ( Trial, etc., formed a complete set of photovoltaic power station network access technologies and management systems, which provided guarantees for the standardized and orderly development of photovoltaic power stations in the province.
