“…Under normal grid condition, the PCS charges and discharges the ESS, and depending on the load or grid states, control the grid current. When a non-linear load is connected, the inverter supplies a sinusoidal current to the load through by using the active power filter control [15][16][17]. In the event of a system fault such as a power failure, the PCS should accurately recognize the grid conditions and supply a stable voltage to the load.…”

Implementation of a smart power conditioning system with a novel seamless transfer method for an energy storage system (ESS) was proposed in this paper. The power conditioning system is to control the power quality or protect the grid system. Therefore, it requires various functions. One of the these functions, the uninterruptible power supply (UPS) function, was applied to proposed power conditioning system. In order for the grid-interactive power conditioning system to continuously supply power to the load, two operation modes are required depending on the grid state. One is the grid connected (GC) mode and the other is the stand-alone (SA) mode. Under normal grid condition, the power conditioning system is operated in GC mode and controls the current. On the other hand, under abnormal grid conditions such as grid outage, the power conditioning system operates in SA mode and supplies power to the load. Unintentional sudden changes in operating mode cause unwanted phenomena (e.g., voltage/current spike, inrush current) which can make system degradation or failure. To improve this situation, the seamless transfer function became necessary. In this paper, by adding seamless function to power conditioning system, it is possible to supply power to the load stably regardless of grid state. In addition, it is possible to prevent secondary accident and to operate stably even if non-detection zone condition occurs by using an active frequency method. The proposed control algorithm was verified through field experiments.

“…However, if the two DGs equally share the compensation efforts, the operation point is located at the area marked by the blue circle on the diagonal dashed line. It can 6 be seen that it may be out of the desirable area. However, in order to make the system operate in the desirable area, the compensation efforts may not always be equally shared by DG units.…”

“…Conventionally, series active power filter can be a solution for compensating unbalances by adding negative sequence voltage in series with the distribution line [3]- [5]. In some works shunt active filters are used to inject negative sequence current to balance the current in the distribution lines and consequently compensate unbalances [6]- [8]. However, all these methods require additional compensation equipment which may increase the total investment cost.…”

, "Tertiary control of voltage unbalance compensation for optimal power quality in islanded microgrids," IEEE Trans. Energy Conv., 2014, IEEE Early access. Abstract-In multi-bus islanded microgrids, the power quality requirements for different areas and buses can be different. This paper proposes a hierarchical control to realize optimal unbalance compensation for satisfying the power quality requirements in different areas. Primary and secondary controllers are applied to realize unbalance compensation for critical bus (CB) and at the same time, to make distributed generators (DGs) equally share the compensation efforts. Tertiary control, which inherently is an optimization method, is implemented to adjust the compensating effort of each DG considering the voltage unbalance limits in local buses and DG terminals. This method realizes multi-power-quality-level control in a multi-bus islanded system by optimally utilizing DGs as distributed compensators and saves the investment for additional compensation equipment. VUFUpper limits of VUF value on LB or DG sides.

“…The repetitive controller can regulate all harmonics with one controller because the harmonics of line current are periodic signals, and the delay caused by the digital implementation can be easily compensated. Applying repetitive controllers to LCs under a typical structure with two parts have been attempted many times [26], [27]. However, as discussed before, LC performance is still degraded by the harmonic extractor.…”

This study proposes a novel one-cycle control scheme with a plug-in repetitive controller for load compensator. The novelty of this scheme lies in the combination of high dynamics and the simplicity of a one-cycle controller and good steady-state harmonic suppression ability of the repetitive controller. In addition, the proposed scheme can reduce the effect of the harmonics in phase voltage for the existence of the repetitive controller. Finally, experimental results on a three-phase, four-wire, three-level load compensator are reported to validate the effectiveness of the proposed control scheme.
