On-grid Microgrid:
ESS plays the role of stabilizer and regulatorin the comprehensive energy utilization of wind,solar power, biomass, gas energy.
Characteristic advantage：
1、Self-use andreduction of dependence on main power.
2、Black start
Off-grid Microgrid:
In remote areas,it is very suitable toestablish an independent PV(wind)+diesel+ESS micro-grid to supply the power tothe user.
Characteristic advantage：
1、MW level orabove off grid power,AC bus scheme improves reliability
2、ESS or dieselgenerator keeps stable voltage and frequency
3、EMS(Energymanagement system ) is used to balance the PV power, wind power and the load
