“…The proposed approach is partially inspired in the EAR applied to autonomous PV systems such as cars powered by solar energy [14] and electric engines coupled to water pumps [15]- [17]. As previously reported by the authors of this paper in [18]- [20] and following a similar way as done in [13], the reconfiguration strategy is based on a controllable matrix of switches configuring the PV modules in a single-string of parallel-connected rows connected to the central inverter.…”

Abstract-This paper applies a dynamical electrical array reconfiguration (EAR) strategy on the photovoltaic (PV) generator of a grid-connected PV system based on a plant-oriented configuration, in order to improve its energy production when the operating conditions of the solar panels are different. The EAR strategy is carried out by inserting a controllable switching matrix between the PV generator and the central inverter, which allows the electrical reconnection of the available PV modules. As a result, the PV system exhibits a self-capacity for real-time adaptation to the PV generator external operating conditions and improves the energy extraction of the system. Experimental results are provided to validate the proposed approach.

“…In these studies, the PV array reconfiguration has been applied to supply the required power to a DC motor coupled with a water pump. This approach was also employed to supply electrical cars with necessary power [15]. The real application of PV cells reconfiguration has been started by Sherif and Boutros [16].…”

a b s t r a c tThis paper applies a new dynamical electrical array reconfiguration strategy on photovoltaic (PV) panels arrangement based on the connection of all PV panels on two parallel groups to reach the 24 V requested by the considered load and providing a maximum output current by connecting in series the two groups. If one of the PV panels or more are shaded, dusty or faulty the connection of the others in the same group will be automatically modified to maintain the requested load output voltage. This dynamical reconfiguration allows also limiting the lost power, due to the incriminate panel, by switching off this panels and reconfiguration the topology. As a result, a real time adaptation of a switch matrix allows a selfability to maintain a constant load voltage. Moreover, a minimum number of PV panels are switched off by isolating the effect of unhealthy panels. In addition, the proposed solution can also be applied for identifying and locating the shaded, dusty and faulty panel. Experimental setup has been built and the results validate the proposed method.

In this paper, we developed a photovoltaic array reconfiguration algorithm to maximize the power that an array can provide a load. The algorithm reconfigures the array such that each element of the array is operated at its maximum power point. A switch topology was also designed to implement the algorithm using the minimum number of switches. Two parameters are used by the algorithm: array loaded voltage and temperature. The algorithm is tested on reconfiguring an array of four photovoltaic panels. The performance of the photovoltaic modules is studied with and without the switching algorithm. Simulations were also done to validate the performance of the system. Tests showed that for a constant resistance load, the algorithm can match the performance of other possible configurations and introduce a significant improvement in the output power of the array. For the constant current load, it was noted that the array can supply the required current at a minimum irradiance while for a constant voltage load, the system performed better than any of the possible configurations.
