“…A method of tuning the PID controller from the location of the poles of the closed loop transfer function is developed by (Abdolmaleki, et al, 2008). These authors presented the closed-loop transfer function of a hydropower plant, proposing the use of the root locus to select the location of the poles which allows the best power plant response.…”

“…Thus, the controller gains should be selected so that the position of the poles causes a dynamic response whose characteristics are as close as possible to the specifications (rise time, overshoot, settling time, etc.) In fact, in previous years many works based on the root locus technique to adjust speed governors have been developed (Abdolmaleki, et al, 2008) (Strah, et al, 2005). Depending on the order of the model, different tuning criteria have been proposed, as is summarized in Table 2.…”

For this purpose, a simplified linearized model is proposed to define some practical tuning criteria for a PI governor by pole placement method (Strah, et al, 2005).…”

The increase in the penetration of renewable energy is a reality in the vast majority of countries, both in Europe and in the rest of the world. This increase is not only occurring in continental power systems, but also on small islands that have high wind and/or solar potential. However, a high renewable energy penetration may compromise the stability of power systems, especially in the case of islands, which constitute isolated power systems. This is due to the inherent characteristics of renewable resources (uncertainty, intermittency and independence between availability and demand). These drawbacks are amplified by the power system inertia reduction caused by the fact that renewable generators are normally decoupled from the grid through a power electronics interface that do not add inertia to the system. It is well known that the long-term variability of renewable energy is well managed by pumped storage hydropower plants (PSHP). Thus, PSHP play an important role in the renewable resources integration,

Future plans for integration of large non-synchronous generation and the expansion of the power system in the Nordic countries are a concern to transmission system operators due to the common interconnections and electricity exchanges among these operative areas. The expected reduction in the inertia anticipates an alteration of the frequency response, provoking a high Rate of Change of Frequency (RoCoF) slopes that can jeopardise the security of the interconnected systems. Since power generation in the Nordic countries such as Sweden, Finland and Norway is hydro-dominated, here, the authors propose a novel solution to tackle this problem including wide area measurements to monitor and share the RoCoF in remote areas with lower inertia to enhance their primary frequency control. To demonstrate the effectiveness of the proposed solution, first a test benchmark control with optimised parameters is developed and later compared against the proposed method. Additionally, since the proposed solution is based on measurements from remote locations in order to guarantee the stability of the system the impact of delays in the communication channels is also included in the problem formulation.
