By June 30, 2019: More than 4,460 MW of solar power was connected to the grid

82 solar power plants, with a total capacity of about 4,464 MW, have been checked for conditions and successfully energized by the National Load Dispatch Center – as of June 30, 2019. These projects are entitled to the electricity purchase price equivalent to Uscent 9.35 / kWh, for a period of 20 years according to the Prime Minister’s Decision 11/2017 / QD-TTg.

Among them, there are 72 solar power plants under the control of the National Dispatch Level (A0) with a total capacity of 4,189 MW; 10 power plants are under the control of regional dispatching levels with a total capacity of 275 MW.

Mr. Nguyen Quoc Trung – Head of Electricity Market Operations (A0) said that as of mid-April 2019, the whole power system had only 4 solar power plants with a total capacity of less than 150 MW. At this point, solar power accounts for 8.28% of the installed capacity of the Vietnamese power system.

The National Load Dispatch Center, regional dispatchers and related units have gathered all resources, 24/24, overtime, excluding holidays, public holidays in the past 6 months, to coordinate effective for investors for projects energizing on schedule.

It is expected that from now to the end of 2019, A0 will continue to energize and put into operation 13 more solar power plants, with a total capacity of 630 MW, bringing the total number of solar power plants in the whole system to 95 houses. machine.

Although it is a valuable addition to the system in difficult power conditions, a large number of solar power plants coming into operation in a short time has caused many difficulties and challenges. for power system operation. The reason is due to the uncertainty, depending on the weather of this type of power source.

In addition, the hot and mass development of solar power projects concentrated in some provinces such as Ninh Thuan, Binh Thuan, Dak Lak has caused grid overload of 110 kV, 220 kV in the above areas. .

According to Mr. Nguyen Quoc Trung, since the beginning of 2018, the Center has coordinated with a number of foreign consulting units to evaluate the impact of renewable energy sources on the system operation. Since then, based on the actual development of renewable energy sources, the Center has continued to monitor, research and recommend and propose to Vietnam Electricity the plans and principles for operation. ensuring constant and stable power supply.

Currently, the Center is investing in a number of systems such as: Expanding the incident recording monitoring system, a large area power monitoring system, building a power quality monitoring system to assess the impact of new types of power sources; building a forecasting system of generating capacity of renewable energy sources to give the optimal mobilization plan, ensuring maximum exploitation of this energy source.
