Model Predictive Control of PV Sources in A Smart DC Distribution System Maximum Power Point Tracking and Droop Control

In a dc distribution system, where multiple power sources supply a common bus, current sharing is an important issue. When renewable energy resources are considered, such as photovoltaic (PV), dc/dc converters are needed to decouple the source voltage, which can vary due to operating conditions and maximum power point tracking (MPPT), from the dc bus voltage. Since different sources may have different power delivery capacities that may vary with time, coordination of the interface to the bus is of paramount importance to ensure reliable system operation. Further, since these sources are most likely distributed throughout\ the system, distributed controls are needed to ensure a robust and fault tolerant control system. This paper presents a model predictive control-based MPPT and model predictive control-based droop current regulator to interface PV in smart dc distribution systems. Back-to-back dc/dc converters control both the input current from the PV module and the droop characteristic of the output current injected into the distribution bus. The predictive controller speeds up both of the control loops, since it predicts and corrects error before the switching signal is applied to the respective converter.

Bus Voltage Control with Zero Distortion for Single Phase Solar Inverters

Single phase voltage source inverters are commonly used for interfacing small distributed generation units to the grid. Instead of reducing the distortion by lowering the loop gain, the new controller employs a digital FIR filter that samples the bus voltage at an integer multiple of the second harmonic frequency. The operating principle and modulation scheme are described. A closed loop control method is developed to enhance twice the line frequency ripple power compensation performance. The guide for the selection of the decoupling capacitance is also discussed. Simulations and experimental results are presented to show the effectiveness of the method. This paper shows that this can be done by using a voltage ripple estimator along with a larger bandwidth for the voltage control loop and additional measures. The filter presents a notch that removes the second harmonic ripple, enabling a design that operates with zero distortion and high bandwidth simultaneously, and is suitable for inverters with small bus capacitors. The proposed controller is tested on a micro inverter prototype with a 300 Wphotovoltaic panel and a 20 u00b5-F bus capacitor.
