Abstract

Distributed generation systems connected to the grid based on the use of renewable energies, due to the power electronics and control systems in the inverters, can perform more tasks than simply providing the maximum active power available to the grid and operating in islanding mode in critical situations. The update of IEEE Std 1547-2018 strengthened this scenario, guiding that the inverters connected to the grid can and should perform other systemic functions, besides simply injecting active power. Thus, despite the existence in literature of inverters with multifunctional characteristics and inverters based on different configurations of impedance source networks, it is observed that the operation of the impedance network arrangements type Y-source dealing with multifunctionality are still unexplored topics with great potential to generate results of relevance. In this sense, the project proposes the exploration and development of multifunctional inverters based on the use of impedance source network type Y-source for distributed micro-generation applications based on the use of photovoltaic renewable energy, considering grid-tie systems and multifunctionality related to the provision of ancillary services. The expected scientific and technological contributions involve the investigation and modeling of the inverter structures with respect to their operational characteristics and their suitability for providing multifunctionality, the establishment of methodologies for the design of the elements of the topologies taking models considering non-idealities (ohmic losses in elements of the impedance network and conduction/switching losses in the power switches). The contributions also involve research and establishment of control strategies based on conservative power theory (CPT) intending multifunctionality related to the provision of ancillary services (harmonics, voltage support, provision of active and reactive power) and functional prototypes. In addition, it is hoped to contribute to the dissemination of knowledge through publications in periodicals, congresses and the training of human resources. (AU)
