Microrredes CC: distribuição de potência e modelo estático com base no controle por droop e MPPT

Abstract

Based on concerns about the growing demand for energy, and its relation to the environment and development, the proposal to implement sustainable development models for the energy sector, established based on the evaluation of energy relations with the concept of sustainability. In this context, government, institutional and research efforts in the search for new energy resources and energy conditioning, grow more every day. The development of microgrids associated with residential, commercial, institutional and governmental buildings, aiming at improving the energy utilization of the installations in the integration of alternative sources of energy, has been highlighted as a technical and economically viable alternative. The present work is inserted in this line, through studies and mathematical propositions applicable to any structure of DC microgrids, considering the most varied types of loads and modes of operation of the local energy sources. In the work is still proposed the study of a two-bus DC microgrid with control of the constituent units through MPPT and droop. The technique used to control bus voltages is through bus signaling. The simulations are implemented in PSIM® software to evaluate the robustness of the control system and to validate the performance of the proposed DC microgrid.
