Probabilistic Analysis of Reactive Power Control Strategies for Wind Farms

摘要: The increasing wind power penetration in electrical systems across Europe has led to rising grid code requirements concerning reactive control by farms order meet the upcoming challenges for system stability, and operation. Some of important factors strategy are stochastic variations voltage which affect both capabilities support demanded code. This master’s thesis concentrates on developing a method probabilistic analysis strategies with aim analyse impact different respect expected annual energy losses, number tap changer operations changing transformers profiles within farms. Based literature study options were identified sequential non-sequential Monte Carlo simulation so-called enumeration studied further detail case study. For this purpose necessary data modeling have been carried out, model generic offshore farm was built tool DIgSILENT PowerFactory. investigations revealed advantages numeration main issues being reliable results losses changes, option include from several years as opposed time sweep far shortest time. proposed applied strategies, regarding usage sources such turbines, FACTS reactors. differences changes illustrated importance strategies. These kind studies useful analyzing future their design control.
