Design of wind-solar and pumped-storage hybrid power supply system

To overcome the inherent defects in wind-solar hybrid system: power generation and electricity load's imbalance because of uncertainty of resources. this article aiming at XJ Group's project design of wind-solar hybrid power supply system, by way of pumped-storage to replace the battery of wind-solar hybrid power supply system, this method can effectively overcome above problems. Wind-solar and pumped-storage hybrid power supply system can reasonable configuration system capacity according to the user's electricity load and resource condition, can ensure system reliability of power supply and reduce the cost of power generation system. Wind-solar and pumped-storage hybrid power supply system greatly suited for plain and the of southern China region with relatively adequate wind energy and solar energy, establish the power system in this region will obtain a very good economic benefits and social effects of energy conservation.
