Predictive Control with Current-Based Maximum Power Point-Tracking for On-Grid Photovoltaic Applications

The high increase of renewable energy sources and the increment distributed generation in electrical grid has made them complex variable parameters, causing potential stability problems to PI controllers. In this document, a control strategy for power injection system from photovoltaic plants through voltage source inverter two-level-type (VSI-2L) converter is proposed. algorithm combines current-based maximum point-tracking (Current-Based MPPT) with model predictive (MPC) strategy, allowing avoidance use controllers lowering dependence high-capacitive value condensers. sections paper describe parts system, algorithms, simulated experimental results that allow observation behavior proposed strategy.
