The system under study is a three-phase voltage source inverter with an LCL filter, and its structure is depicted in Fig.~ ef{fig:struct}. The inverter converts DC power from a DC bus  into AC power required by a load. As the system is intended for AC distributed generation, an LCL filter is used to damp the high order harmonics introduced by the inverter in order to comply with power quality standards ({em e.g.} IEEE1547 and IEE519, see~cite{IEEE1547}~and~cite{IEEE519}). $V_{DC}$ is the voltage of the DC-bus and  $Z_L$ represents a generic load.  The DC-Bus voltage is considered as a known variable of the inverter, regardless the way it is generated and regulated. At the point of common coupling (PCC), the inverter+filter module is connected to the load (which is generally  another system) represented as $Z_L$.
