Variable speed hydropower plant with virtual inertia control for provision of fast frequency reserves

In this paper, five virtual inertia control structures are implemented and tested on a variable speed hydropower (VSHP) plant. The results show that all five can deliver fast power reserves to maintain grid stability after disturbances after a disturbance. The VSHP is well suited for the purposed since its output power can be changed almost instantaneously by utilizing the rotational energy of the turbine and generator. This will cause the turbine rotational speed to deviate from its optimal value temporarily. Then the governor control will regain the turbine rotational speed by controlling the guide vane opening and thereby the turbine flow and mechanical power. With that, the VSHP output power can be changed permanently to contribute with primarily frequency reserves. Dynamic and eigenvalue analyses are performed to compare five different versions of the basic VSG and VSM control structures; VSG, power-frequency PID-controller with permanent droop (VSG-PID), VSM, VSM with power-frequency PD-controller (VSM-PD), and VSM with power-frequency PID-controller and permanent droop (VSM-PID). They are evaluated by two main criteria; their ability to deliver instantaneous power (inertia) to reduce the rate of change of frequency (ROCOF) and their contribution to frequency containment control (steady-state frequency droop response

Enacting citizenship through writing: an analysis of a diary written by a man with Alzheimer’s disease

Citizenship and dementia studies have, during the last 15 years, grown into a substantial body of research recognising the experiences and agentic powers of people living with dementia. This article aims to contribute to and extend this research field. We undertake the aim through a feminist posthumanist non-representational analysis of a diary written by a man with Alzheimer's disease to explore the diary's potential to enact citizenship. The first section of the article examines current approaches to democracy, citizenship and dementia, and advances the concept intra-active citizenship, an approach that extends the individual and understands citizenship as enacted in and through entanglements of human–more-than-human agents. The second section is a theory-informed analysis of the diary, in which events, relations, doings and affective resonances constitute the analytical categories. The third section discusses whether the diary and the writing of it might enact citizenship, and if so, what kind of citizenship. The article concludes with a reflection on how our posthumanist, non-representational approach might pave a new path for theorising and, hence, contribute to new understandings of dementia and citizenship
