In this paper, we identify the current status and outlook of the renewable energy source in Morocco. We provide also the challenges and the barriers to the development of renewable energy (RE) in Morocco and the national strategy for energy security and meeting these challenges. Then, using a time series method, we estimate the capacity of the wind and solar power in Morocco plans in the long-term towards 2030, that can be injected without creating the constraints of transit on the grid utility and on the whole electrical system.

Based on the advantages of doubly fed induction generator (DFIG)-based wind turbine (WT). This paper proposes a new control strategy to improve the ride-through capability of DFIG-based WTs in the event of a grid fault. The proposed method is performed by using the DFIG converters control and the addition of the damping resistances connected to the DC circuit, to follow the requirements defined by the grid codes. The proposed ride-through solution limits the peak values of the DC link voltage, the rotor inrush current, electromagnetic torque and DFIG transient response at the times of occurrence and clearing the fault. The proposed solution is simulated and compared with the crowbar solution using MATLAB/Simulink environment. Keyword:Damping INTRODUCTIONWind energy is gaining increasing importance throughout the world. This fast development of wind energy technology has large implications for a number of people and institutions. As WTs become larger and level of penetration becomes higher in electrical power systems, grid operators have modified the grid codes. According to these new grid codes, WTs must remain connected to the grid and supply reactive power to guarantee the grid voltage during the grid faults. This ability of WTs is called the fault ride through (FRT) capability [1], and more specifically for voltage dips, low voltage ride through (LVRT) capability [2], [3]. Nowadays, DFIG is the most used generator for WTs due to the advantages of variable-speed ability, higher energy capture, improved power quality and using converters rated for partial-scale converters [4]. On the other hand, because the stator of the DFIG is directly connected to the grid, it is very sensitive to the grid disturbances, particularly voltage dips [5]- [12]. The transients voltages on rotor side during grid faults, are higher than the stator side, and thus the rotor side converter (RSC) and intermediate DC circuit are particularly susceptible to be destructed due to voltage transients. Also, the voltage sag at the stator terminals due to the grid faults causes the rotor over-currents, DC-link over voltage and torque oscillations that could lead to destruction of the power converter and mechanical parts. So, without a proper control strategy, the DFIG is unable to stay connected to the grid during the grid faults [5]. Likewise, the DFIG system is not controlled during the critical time of grid faults and the system cannot support the grid. Previous approaches of researches have been presented to address DFIG FRT issues. The most common FRT solution is to short circuit the rotor windings with the crowbar circuit [6]- [7]. When the rotor over-current is detected, The crowbar circuit short circuits the rotor windings when the rotor overcurrent is detected, which isolates the

The present article focuses on the calculation of the wind capacity credit by integrating the Moroccan project on the wind energy of 1000 MW in 2020. After an introduction to the Moroccan Integrated Wind Energy Project, a wind capacity credit assessment program will be implemented on Matlab software including the whole information about “installed capacity, number of plants, failure rate, types of installed units, peak demand etc.” This program will be used to calculate the safety rate of an electrical system as well as the capacity credit of Morocco’s electricity production network. This section will be built in two phases: the first phase will examine the impact of TAZA wind farm with an installed power of 150 MW, while the second phase will focus on the generalization of this study on all the wind farms that will be injected to the Moroccan grid in 2020. The research provides conclusion according to comments and assessment of the impact of this electric energy integration based on the wind generation.
