“…The OHC is usually applied for loads with wider or unknown harmonic spectrum, where harmonics of unpredicted orders may appear [32]. One advantage of this method is that it is only necessary to employ one harmonic extractor [33] to separate the fundamental current from the load current.…”

Plug-in Electric Vehicles (PEVs) will remain connected to the grid a high percentage of their life-time. During these connections, idle-time will be considerably longer than battery charging time. This fact turns PEV idle-time into a suitable candidate to help in the distribution grid management by implementing active distribution grid functions, leading to the future Smart Grids. In this chapter, conventional ancillary services for distribution grids are presented, including their development in the new context of Distributed Energy Resources (DER), micro grids, smart grid and either in connected or isolated modes. Later, the coordination of the previously discussed services with PEVs is analyzed, mainly considering them as Energy Storage Systems. Then, the optimization problem is presented, empathizing the indexes and constriction that could be taken into account. From the optimization procedure, reference operation setpoints are generated for each individual PEV. Then, the coordination of charger operations for maximizing global impact on the whole distribution grid is developed. Control strategies are presented and analyzed in terms of their operation setpoints in normal and abnormal grid states, when they are expected to control active, reactive and harmonic power. Finally, some examples on how the described strategies can be used for controlling active, reactive and harmonic power using a PEV charger, when the PEV is following the given operation references, are discussed.

“…However, two different control strategies can be employed, to compensate harmonic currents in terms of bandwidth [32]: overall harmonic compensation (OHC) or selective harmonic compensation (SHC). In both cases it is always necessary to check that the charger capacity is not exceeded.…”

“…With the use of HDN, the filter transfer function of a channel is given by (10) to n channels where D j is the customized version of the transfer function (3) to k j = k j and ω j = j * ω, and ω the fundamental frequency detected by the FLL.…”

“…Active filters with selective compensation of harmonics has some advantages compared to total compensation of harmonics, such as the drastically reduced bandwidth and the lower possibility of occurrence of dangerous oscillations between the filter and the load due to the presence of capacitive or resonant components on the load [8], [9], [10]. In medium/high-power systems where the switching frequency of the active power filter is low to avoid power loss, the selective harmonic compensation become especially important, since traditional high frequency active filters cannot be used [11].…”

-This paper proposes the application of an accurate, fast and stable method to be used by the control systems in the selective compensation of harmonic currents in three phase systems susceptible to frequency changes and phase jumps. This application is based on a MSOGI-FLL (Multiple Second Order Generalized Integrators -Frequency Locked Loop) method, which is composed of multiple double adaptive filters called Dual Second Order Generalized Integrators (DSOGI) coupled to the frequency detector entitled Frequency Locked Loop (FLL) which keeps the set synchronized, even in abnormal situations.

“…Several national and international standards define the quality limits of the local bus voltage and the maximum limits of current harmonics injected by DPGS [3]. Especially in weak or isolated grid structures Active Infeed Converters can be used to enhance the quality of the local bus voltage in terms of harmonic distortion and balancing the reactive power locally [4]. This active filter functionality can be integrated into DPGS systems as well.…”

The capability of harmonic compensation gains more importance in future grids. As local density of installed distributed power generator systems is increasing, the examination of the control behavior of parallel operating inverters is crucial. In this paper the performance of different, commonly discussed harmonic compensation algorithms for parallel acting inverters in an isolated microgrid is investigated and compared. Similar and different harmonic compensation algorithms in each autonomously controlled inverter are evaluated. Dynamic and stationary performances are considered based on different scenarios for harmonic compensation.
