In the UK power system, there is currently no battery energy storage system (BESS) for providing grid-scale frequency response. However, according to the UK future energy plan, with a high penetration of renewable energy sources, battery technologies have become increasingly attractive to provide firm frequency response (FFR). This paper estimates the current and future balancing requirement of National...
Wind speed variability generates the main challenges for grid integration of wind power. Worldwide, requirements governing generator connection to the transmission grid evolve as the modern energy industry continues to develop. With increased wind power penetration, wind power plants are required to provide grid support and control actions similar to conventional power plants. Dedicated control systems...
A power system's AC frequency is a system-wide indicator of the immediate power balance in the system. This is used by selected generators to adjust the generation to level out imbalances continuously, as well as in the case of disturbances in the system. However, previous theoretical and empirical studies indicate that this service might as well be provided by demand-side control. In this paper we...
The increasing wind penetration in today's power grids has led to growing interest in the frequency control capabilities of wind generation. Several publications have assessed this subject, proposing a variety of methods both on the levels of a single turbine and of a wind farm. This paper focuses on the role of wind generation in a system's primary frequency response. Wind turbine control methods...
New control systems for Variable Speed Wind Turbines (VSWT) need to be developed in order to provide inertia response and frequency control to support the grid. This work studies the behavior and capability of VSWT for providing temporary active power overproduction. The study is conducted on a multi-megawatt VSWT with Doubly-Fed Induction Generator. It was found that it is possible to have an active...
Since the electricity industry unbundling, frequency control has became a service. It is mainly provided by synchronous generators connected to the transmission grid. Nevertheless, other synchronous entities (electric systems and offshore wind farms), which are not synchronously linked to the main interconnection, could technically contribute to the frequency control. Their participation is conditioned...
