<div>The changing energy landscape due to the large scale integration of renewable energy and shutting down of conventional thermal plants has opened up the potential of alternate sources in the blackstart services market. Grid forming wind turbines can do controlled islanded operation independent of an external grid voltage and thus, participate in network restoration from the start. However, it is necessary to study the capability of wind turbines to deal with the demanding energization transients in a controlled and stable manner. This work investigates the feasibility of using virtual resistance in the wind turbine converter control to reduce transients during self-transformer inrush and sympathetic interaction from downstream string transformers. This can eliminate the need for pre-insertion resistors during sequential energization. The sensitivity of the AC current and voltage output along with DC link transient to the virtual resistance parameters has also been analyzed using PSCAD simulations. Finally the effectiveness of the proposed method for offshore network energization by a grid forming wind power plant has been tested by comparing to results for a pre-insertion resistor.</div>

Increasing large-scale integration of renewables in conventional power system has led to an increase in reserve power requirement owing to the forecasting error. Innovative operating strategies are required for maintaining balance between load and generation in real time, while keeping the reserve power requirement at its minimum. This research work proposes a control strategy for active power balance control without compromising power system security, emphasizing the integration of wind power and flexible load in automatic generation control. Simulations were performed in DIgSILENT for forecasting the modern Danish power system with bulk wind power integration. A high wind day of year 2020 was selected for analysis when wind power plants were contributing 76.7% of the total electricity production. Conventional power plants and power exchange with interconnected power systems utilize an hour-ahead power regulation schedule, while real-time series are used for wind power plants and load demand. Analysis showed that flexible load units along with wind power plants can actively help in reducing real-time power imbalances introduced due to large-scale integration of wind power, thus increasing power system reliability without enhancing the reserve power requirement from conventional power plants.

Despite of the political and economic problems wind power continues its steady development, the main directions of which are presented in the paper. New production facilities and materials are being created, which contributes to increased efficiency by enlarging the unit capacity of wind power plants (wind turbines) and reducing the unit cost of energy production. A promising large-scale direction of modern wind power is offshore wind power plants operating on the offshore shelf, for which the production of 6–8 MW wind generators is developed. Many offshore wind turbines manufacturers prefer a direct-drive permanent magnets synchronous generator, while they managed to achieve 25 kg/kN·m for the torque to the mass ratio and are searching how to reduce wind plants cost by various ways. The most significant achievements in the industrial wind turbines production and wind plants construction, as well as promising projects providing non-standard solutions, including those based on superconductivity, are presented.
