Yuzhu Peak is 6,178 meters above sea level and is the highest peak in the eastern section of the Kunlun Mountains. It is located near the Kunlun Pass 160 kilometers south of Golmud city, Qinghai province.The base camp of Yuzhu is at an altitude of 5,000 meters and can be reached directly by vehicle.
This is because the peak-valley mechanism is still insufficient to identify all potential spikes in power supply, so the storage and reserve capacity resources cannot reach the efficient allocation. As a result, to encourage storage and reserve capacity, peak-valley mechanism that more accurately coordinate supply and demand is needed.
The combined operation of hybrid wind power and a battery energy storage system can be used to convert cheap valley energy to expensive peak energy, thus improving the economic benefits of wind farms.
They can be charged when energy is less expensive and used during peak demand periods. Energy storage batteries can use various types of batteries such as lithium-ion, flow, or sodium-sulfur batteries. Energy storage systems are used in the power grid to solve imbalances between electricity demand and supply.
