“…Also in this scenario, the PI regulator is initially tuned so to show a dynamic performance as similar as possible to the H ∞ and SM. Then, 1,000 simulations are performed for each case, and the results of the standard deviations of the bus frequency, σ ω , and the highest variation 3 With this aim, the technique to estimate bus frequencies is the one proposed in [30].…”

Abstract-This paper describes the modeling and formulation of a variety of deterministic techniques for energy storage devices, namely the PI, H-infinity and sliding mode controllers. These techniques are defined based on a general, yet detailed, energy storage device model, which is accurate for transient stability analysis. The paper also presents a thorough statistical comparison of the performance and robustness of the considered control techniques, using stochastic dynamic models and a variety of disturbances and scenarios. The case study is based on a 1,479-bus model of the all-island Irish transmission system and an energy storage device actually installed in the system.

“…SMES systems have attracted the attention of both electric utilities and the military due to their fast response and high efficiency (a charge/discharge efficiency over 95 %) [4]. The most important advantages of SMES devices include high power and energy density with outstanding conversion efficiency, unlimited number of charging and discharging cycles, much longer lifetime compared to the battery storage systems and fast and independent power response in four-quadrants [5,6]. As a new sample work, in [7] the SMES was used as a single source for distributed generation and a new controlling method was introduced but there was not addressed a hybrid source for DG.…”

A combined power source including superconductor magnetic energy storage system (SMES) and photovoltaic (PV) systems has been considered for distributed generation system as a hybrid power source in this research. Both power sources have been connected to power grid and some controllers have been designed for power injection control. The SMES system can be in charging mode via PV system and power grid. Moreover, power injection controller has been designed for tuning of produced power of PV and SMES system. For this aim, a DC/DC converter has been connected to PV system and a bi-directional-three-level chopper has been used for SMES. PV power control has been based on the DC/DC converter control and the chopper control has been used for SMES power control. On the other hands, inverter control has been confirmed for injection of active/reactive power from distributed generation system to power grid. Proposal of a new scheme and design of a novel controller, are the advantages of this research. Finally, a series of simulation results have been shown.Keywords PV system · SMES · Bi-directional-three-level chopper · Chopper switching · Three level inverter · Power injection List of symbols AThe ideal coefficient related to photovoltaic cell model The current source related to photovoltaic system model I SC The short circuit current of the diode used in the photovoltaic cell model I RS The short reversed saturated current of the diode used in the photovoltaic cell model K Boltzmann constant K IThe temperature effect coefficient on the current of used diode in the photovoltaic cell model N sThe number of series cells in photovoltaic package N pThe number of parallel cells in photovoltaic package P PVThe power of photovoltaic system P T rThe transmitted active power from the distributed generation system into the power grid P PV -Max The maximum accessible power from the photovoltaic system qThe numerical value of electron Q T rThe transmitted reactive power from the distributed generation system into the power grid R sThe series resistor of each diode in photovoltaic package R shThe parallel resistor of each diode in photovoltaic package T cThe temperature of the environment in photovoltaic system T re fThe reference temperature in photovoltaic system model V c1 , V c2 DC-link capacitors voltage V DC
