TL;DR: In this article, a control strategy is proposed to achieve decentralized power management of a PV/battery hybrid unit in a droop-controlled islanded microgrid, where the PV unit is controlled as a voltage source that follows a multi-segment adaptive power/frequency characteristic curve.
Abstract: In this paper, a control strategy is proposed to achieve decentralized power management of a PV/battery hybrid unit in a droop-controlled islanded microgrid In contrast to the common approach of controlling the PV unit as a current source, in the proposed strategy, the PV unit is controlled as a voltage source that follows a multi-segment adaptive power/frequency characteristic curve The proposed power/frequency characteristics, of the hybrid unit and of the whole microgrid, adapt autonomously to the microgrid operating conditions so that the hybrid unit may supply the maximum PV power, match the load, and/or charge the battery, while maintaining the power balance in the microgrid and respecting the battery state-of-charge limits These features are achieved without relying on a central management system and communications, as most of the existing algorithms do The control strategy is implemented using multi-loop controllers, which provide smooth and autonomous transitions between the operating scenarios Small-signal stability of the proposed control loops is investigated, and the system performance is experimentally validated on a 35 kVA microgrid

TL;DR: A low-cost receiver for a commercial PLCC system is described and demonstrated, demonstrating the feasibility of PLCC-based islanding prevention and considerations for maximum anti-islanding effectiveness.
Abstract: Islanding of grid-connected photovoltaic (PV) power systems jeopardizes personnel and equipment and must therefore be prevented. Existing islanding prevention schemes are undesirable because they fail for certain relatively common customer loads and when more than one PV power system is present, degrade PV power quality, reduce system efficiency, and increase system complexity. These problems can be overcome using power line carrier communications. (PLCC) and an inexpensive, purpose-designed receiver. The use of PLCC for islanding prevention is discussed. In this paper, including considerations for maximum anti-islanding effectiveness. Also, a low-cost receiver for a commercial PLCC system is described and demonstrated. This receiver demonstrates the feasibility of PLCC-based islanding prevention.
