Abstract

This work is an overview of one of the renewable energy sources, wind power. The high cost of testing wind turbines and analyzing their characteristics in research laboratories prompted us to create the Wind Emulator. In this article, we will proceed with the development of an emulator of a wind turbine conversion chain based on an asynchronous machine. This emulator would be capable of faithfully reproducing the dynamic characteristics of a real wind turbine and of integrating them optimally into a real electrical system so as to be able to study its operation at laboratory level, so our objective is to have an emulator that will provide the characteristics (speed-torque-current) in real time and with realistic conditions. Our development approach is based on the use of two classical control strategies under the MATLAB/Simulink closed-loop environment: direct torque control (DTC) and indirect rotor flux vector control (IRFOC) in dynamic and static regimes. The simulation results presented and discussed in this work enable us to determine the operating limits of our proposed wind emulator, in order to validate the most suitable emulator model. Ultimately, this model will be integrated into an intelligent computing board such as the DSP1104.

Abstract

In Morocco's electrical grid, the percentage of renewable energy used is rising. This growth can have significant impacts on the electrical system's ability to meet load because of unpredictable solar energy production. To evaluate the effects of concentrated solar power (CSP) generation and load evolution on the hierarchical level I (HLI: the capacity to cover the load on the premise of an endless node), this study is evaluating, by employing a Monte Carlo non-sequential simulation, decreasing the impacts on the ability and increasing the reliability of the Moroccan electrical grid. For that, we determine the CSP based on the hourly direct normal irradiation (DNI) for each site, the hourly conventional generation and the hourly load. Then we use these data as input elements in the Monte Carlo simulation to calculate the reliability indices like loss of load probability (LOLP), loss of load expectation (LOLE) and loss of energy expectation (LOEE).
