Renewable energy deployment is currently advocated globally as a key component in providing access to green energy, addressing current climate change and increasing energy services as well as creating economic opportunities. Wind power generation is one of renewable energy sources which are gaining more interest as a generation source to inject more power capacity to power system grid. This is as a result of the fluctuation of fuel prices affecting thermal power and unfavorable weather conditions affecting hydropower plants. According to world wind energy association, the total world wind power installed capacity had reached 651GW by end of 2019 and is estimated to reach 8% of world electricity market by 2035. Many governments in the world today have enacted policies to promote renewable energy rollout to meet the ever increasing electricity demand and reduce dependence of power from hydro and thermal plants.Wind induction generators are non-conventional and use different technology and their output depend on changing weather conditions. This generates power quality challenges such as uncontrollable reactive power and voltage fluctuations which negatively affect power system voltage stability. Since the rate of connecting wind power plants into transmission power systems is increasing rapidly, there is need to investigate their impact on power system voltage stability. This in turn will help power system operators and planners in their daily power system operations. This paper aims at analyzing the impact of wind power integration on power system voltage stability. Line stability Index ( ) and Fast Voltage Stability Index (FVSI) were used to analyze voltage profiles. These line voltage indices show the proximity of transmission lines to voltage instability state. IEEE 30 bus system was used as a test system to carry out this research study. The research also investigated the effects of different location and different penetration levels of wind power into the power system using MATLAB simulation software.

“…In the case of [7], [8], and [9] use is made of a Permanent Magnet Synchronous Machine and a torque control; the steady state experimental results guarantee the correct functioning of the system, however, it is highlighted that in [7] and [8] inertia is not included; while [9] addresses inertia compensation and illustrates its dynamics in the face of torque changes, and it also contemplates tower shadow and wind shear phenomena (differences in wind speed due to tower and to the vanes position). Other proposals of emulators make use of the Squirrel Cage Induction Machine (SCIM), as is the case of [10] and [11]; in the case of [11], among other things, it addresses various types of turbine and does consider inertia compensation. Steady state results are good, but no transient analysis associated with inertia compensation is shown.…”

This work presents the design and implementation of a wind turbine simulator to carry out laboratory tests on the generation, regulation, and control of a wind power conversion system (WECS) with a capacity of 3 kW. A three-phase squirrel-cage induction motor emulates the static and dynamic wind turbine characteristics based on the torque-speed profile of a wind turbine. The Emulator allows all electromechanical tests to be carried out, from the characterization of the generator to the adjustment of controls and protections for equipment operating in a specific location. Initial Emulator tests were successful.

Wind energy has the fastest and highest growth rate of any other Renewable energy sources (RES). Investigating the Wind Energy Conversion Systems (WECS) is very important for improving efficiency. However, It is required a monumental accessible land space for installing Wind turbines(WT). Consequently, this paper presents the design and implementation of a Wind turbine emulator (WTE) to substitute WTs. The proposed WTE includes a new Maximum Point Power Tracking(MPPT) technique based on integrating binary search technique and genetic algorithm. The proposed emulator has an SQLite database as a repository of wind turbine information. Also, it has a graphical user interface(GUI) to facilitate the operation. System components have been modeled and simulated using MATLAB Simulink. Furthermore, a prototype is implemented based on a series excited DC motor and permanent magnet synchronous (PMSG). All static and dynamic characteristics have been investigated to prove the capabilities of the developed emulator. Also, an integration test has been conducted on real-time conditions of wind speed profile and working load for 24 hours to check the reliability. The experimental results are compared with the simulation results for validation and showed the capability of the proposed WTE of emulating a wide range of Wind turbines.
