Why China's solar power grid integration difficulties
When the power suddenly lost a part of solar power (such as when suddenly a cloudy rain area, also need emergency dispatch) power generating units to start or increase the power, problems also exist for grid security. Therefore, China's current power grid can only withstand the solar energy and wind power capacity of 20% or less.
When the sun is strong, the grid will need to stop some of the generating units or reduce the power generation capacity of some of the generating units, a part of the load from the solar power supply. And when the night or cloudy, you need to start the generator set or increase the output of the generator unit, to supplement the loss of solar power capacity
China's solar power is not difficult, in fact, most of the country's solar power grid have the same difficulties. This is because: solar power is phased, subject to weather restrictions.
