| Abstract |
Grid stability is one of the main concerns in renewable energies. The\n lack of inertia and their low capability to provide frequency support\n has created the need for implementing new control strategies to solve\n this problem. In current networks, frequency and voltage support are\n performed through synchronous generators, which provide an inherent grid\n support due to the inertia presented in their mechanical rotors. Based\n on the same concept, renewable energies based on power converters have\n introduced synchronous controllers to emulate the dynamic behavior of\n synchronous generators and provide voltage and frequency support.\n However, most synchronous control strategies integrate their controllers\n as an add-on firmware embedded in each power converter, without\n presenting a coordinated synchronous performance when several converters\n operate in a PV power plant. The aggregation of several power converters\n operating with a coordinated synchronous response would be advantageous\n in these cases, since they can provide a harmonic response with an\n automatic power distribution when grid support is required. This paper\n presents a synchronous control strategy for photovoltaic power plants,\n which manages several power converters as an aggregated synchronous\n system. |
