This paper presents a simulation of a grid-connected photovoltaic power system. A complex model of power distribution system is developed in MATLAB Simulink, then it will be simulated to determine an amount of power delivered to the grid based on irradiance and temperature. Solar irradiance data collection is conducted using a solar irradiance meter. These weather data (solar irradiances and temperatures) are transformed into signal inputs and model through a grid-tied Photovoltaic (PV) model system which consists of PV, incremental conductance Maximum Power Point Tracking (MPPT) method, DC-DC boost converter, inverter, voltage source converter (VSC) control algorithms, and grid equipment. The output variables can be related to current, voltage or power. However, tracing of the current-voltage (I-V) characteristics or power-voltage (P-V) characteristics are the vital need to grid-tied PV system operation. Changes in solar irradiance and temperature imply changes in output variables. Detailed modelling of the effect of irradiance and temperature, on the parameters of the PV module and the output parameters will be discussed. With the aid of this model, one can have a feasible idea about the solar energy generation potential at given locations. This comprehensive model is simulated using MATLAB/Simulink software.

As the penetration of the Wind Energy Generation System (WEGS) into the modern power systems is extensively increased, an efficient control strategy of a WEGS plays an essential role in wind power utilization. This study presents Sliding Mode Control (SMC) design for the Variable Speed Wind Farm Systems (VS-WFS) based on Permanent Magnet Synchronous Generator (PMSG) and interconnected to the electric network. The proposed control laws are used to regulate both grid-side and generator converters. The generator side converters are used to track the maximum wind power. The function of the grid side inverter is to transfer the total extracted wind power from DC-link to the electric network and regulate the DC-link voltage. A SMC scheme is developed in the sense of Lyapunov stability theorem for the VS-WFS. Besides, the effectiveness of the proposed SMC scheme is demonstrated by comparison with a traditional Proportional Integral (PI) control strategy for fault conditions as well as for normal working conditions. Simulation results with Matlab/Simulink environment are presented to support the theoretical considerations demonstrating the potential contributions of both control strategies. The proposed SMC scheme can provide excellent control performance than the traditional PI strategy.

This paper discusses two techniques based on the feedback linearization (FBL) method to control the active and reactive output powers of three-phase grid-connected photovoltaic (PV) inverters. The first control scheme is an application of the direct FBL approach. The other is an appropriate combination of the FBL and fuzzy logic (FBL-FL), and is the main proposed method of this study. Wherein, a unique fuzzy logic controller (FLC) is designed to enhance effectiveness of the linear control method used in the direct FBL. In detail, its major objectives are to improve the transient response and reduce steady-state oscillations in the output powers. In this research, the illustrative PV inverter utilizes a three-level DC-AC converter, an R-L filter and a 250 V/10 kV wyewye transformer to inject the energy, obtained from PV array with a nominal power of 100 kW, into the 10 kV/60Hz three-phase grid. Numerical simulations in MATLAB and PSIM illustrate that the two FBL-based structures perform very well in independently regulating the active and reactive output powers to the reference values, even within the parametric uncertainties and the unbalanced grid voltage condition. Moreover, comparisons of simulation results, obtained from the traditional proportional-integral (PI) control and the two FBL-based structures, show advantages of the proposed FBL-FL hybrid technique in terms of fast response, small overshoot, acceptable steady-state fluctuation and high robustness.
