Energy Management Strategy and Adaptive Control for SMES in Power System with a Photovoltaic Farm

Abstract

-This paper proposes an energy management strategy and adaptive control for superconducting magnetic energy storage (SMES) in a distribution power system with a gridconnected photovoltaic (PV) farm. Application of the SMES system can decrease the output power fluctuations of PV system effectively. Also, it can control the real and reactive powers corresponding to the scheduled reference values with adequate converter capacity, which are required at a steady-state operating point. Therefore, the adaptive control strategy for SMES plays a key role in improving the system stability when the PV generation causes uncertain variations due to weather conditions. The performance of proposed energy management strategy and control method for the SMES is then evaluated with several case studies based on the PSCAD/ EMTDC ® simulation.

A survey on power management strategies of hybrid energy systems in microgrid

“…In the present situation, Battery based Energy Storage Elements play prominent role in Power management mainly in isolated microgrids. Different energy storage devices such as SMES,CESS were addressed in [31,32]. In [33] wireless power management with battery.…”

“…The active reference power Pref from equation (5) to be injected into thegrid is calculated as follows:…”

“…The last years have seen gradually an expansion on application in the storage energies, through all storage energies, the SMES (Superconducting Magnetic Energy Storage) is placed in this group, the SMES is coil which is in a superconducting state at cryogenic temperature, this means that the energy losses during the operation is almost zero [1][2][3][4][5], the SMES is an electrical energy that stores the energy in the magnetic field ,it has the Ability to rapidly release stored energy, very high storage energy, Quick to recharge (millisecond) with high efficiency and almost infinite cycle life, also the SMES used to control the active and reactive power, used to the transmission and distribution system stability and stabilize system frequency [6][7][8].…”
