“…Due to utilizing higher frequency signals, the reaction of the MPPT system is much faster and it results in faster transient response. This method does not guarantee to find In [73], researchers used the mathematical model of the system to calculate the output current of the solar panel. Similar to any other model-based method, dependency on the accurate model of the system is one of the main concerns in these types of methods.…”

This thesis presents a novel Maximum Power Point Tracking (MPPT) technique for photovoltaic (PV) solar panels. The proposed method eliminates the need for current sensing by injecting high-frequency perturbations and monitoring the behavior of the system. The method takes advantage of the increase in the non-linearity of the I-V curve of the solar panel in order to find the maximum power point (MPP). Current sensors are a costly component in the design of a power converter. They also require a signal conditioning circuitry to reduce the noise and prepare the signal to be sampled and used by the controller. This elimination can reduce the cost of MPPT circuitry. The proposed method also shows a very fast tracking response due to the use of high-frequency signals instead of relying on low frequency and DC signals which are used in the traditional methods. Numerical analysis, simulation results, and experimental results verify the feasibility of the proposed technique.An FPGA controlled converter is designed for the experimental implementation of this technique.The board is designed to be expandable and versatile in order to be used as a development board for power electronics applications.

“…To provide a contrast with the proposed strategy, a simulation is shown in Figure 5, in which the reference voltage is obtained from P&O MPPT strategy [24] with a 1 ms step for the MPPT and voltage reference changes ∆v of 0.1 V. The current reference i q (s) is considered to be 0 (no injected reactive power). The constant G ac corresponds to the converter gain, equal to 0.5.…”

“…It is based on producing disturbances in a variable that operates as an actuator and subsequently evaluating how the power of the system evolves. It is possible to find different variations of the P&O strategy, where the variable to be modified will mainly depend on the energy storage element available in the power converter used [24]. For voltage source-type inverters, voltage disturbances are typically created, because the DCside capacitor operates as a voltage stabilizer [25,26].…”

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