Validity of a Wearable Digital Insole for Assessing Gait ON and OFF in Parkinson's Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Gait impairment is a distinctive symptom of Parkinson's disease that negatively impact mobility. We assessed the validity of wearable digital insoles against a validated reference gait analysis system for measuring select gait characteristics in patients with Parkinson's disease. Methods A comparative analysis between digital insoles

A Market Clearing Mechanism Considering Primary Frequency Response Rate

IEEE Transactions on Power Systems, 2021
Prior-art market mechanism designs in the literature do not well distinguish the primary frequency reserve resources with different response rates. This letter proposes a performance ratio that quantifies the relative effectiveness of generators and flexible demand resources in frequency regulation considering their response rates.

Economic impact of wind integration on Primary Frequency Response [PDF]

2015 IEEE Eindhoven PowerTech, 2015
In order to have a reliable and secure power system, frequency stability should be guaranteed. Primary Frequency Response (PFR) is used to arrest the frequency deviation upon a contingency. The significant penetration of wind generation in power grids has negative effect on the PFR, as the contribution of wind machines to the total system inertia is ...

Probabilistic assessment of wind generation effects on primary frequency response [PDF]

2011 IEEE Trondheim PowerTech, 2011
In modern power systems wind is one of the main sources of renewable energy. This is especially true in the case of small systems where frequency issues are often observed. Due to this fact, limits are imposed on the maximum allowable wind penetration level, commonly based on a worst case scenario approach. This however does not give a complete picture
