What Is The Relationship Between Energy Storage Connectors And New Energy?
What is the relationship between energy storage connector and new energy?
The power system is always in a state of dynamic balance, and has high requirements for stability. Traditional thermal power can adjust its output according to the needs of the power grid, but wind power and photovoltaic power have to "rely on the weather" and have natural volatility and unpredictability. High volatility of output will increase the safety risk of power grid operation.
This is easy to understand. The efficiency of photovoltaic power generation is only based on light. It fluctuates with the rising and setting of the sun every day. It usually reaches its peak at noon and the output is 0 at night. In addition, sunny days and cloudy days are different, and there are also differences between different seasons.
An organization has calculated a 50MW photovoltaic storage power station in Golmud. On sunny days, the output power can reach 41.8MW, and the actual daily power generation is 234,400 KWh. The above data are 31.6MW and 136,200 KWh on cloudy days.
The output of wind power can fluctuate by up to 80% during the day. Compared with photovoltaic power, its output peaks around midnight and gradually declines from the morning. This is a perfect mismatch with the power consumption cycle and has a typical "reverse load" attribute.
At this time, a role similar to a reservoir is needed to adjust the center, and battery storage connector was invented.
Output power when the output is low and absorb power when the output is peak. The storage connector system can not only smooth out the volatility of new energy power generation, but also reduce energy waste.
