Energy storage (ES) is a flexible resource and can effectively relieve the pressure on the power grid during peak hours and improve the ability to consume new energy. Due to the high cost of ES, a practical and important business solution is a lease, i.e., the ES owner leases the ES to lessors such as grid operators and wind farms. However, a well
With the transformation of China''s energy structure, the rapid development of new energy industry is very important for China.
