Kilic, H. (author), Khaki, Behnam (author), Gumus, Bilal (author), Yilmaz, Musa (author), Palensky, P. (author)In recent years, there has been an increasing interest in the integration of photovoltaic (PV) systems in the power grids. Although PV systems provide the grid with clean and renewable energy, their unsafe and inefficient operation can affect the grid reliability. Early stage fault detection plays a crucial role in reducing the operation and...conference paper 2020

Gusain, D. (author), Cvetkovic, M. (author), Bentvelsen, Ron (author), Palensky, P. (author)To counter the inherent intermittent and unpre dictable power generation from large amounts of wind and solar, fast-acting resources are required, one of the options being sector coupling via power to gas devices. Industrial Power to Gas (IPtG) resources, such as an electrolyzer, represent an attractive solution to satisfy the rising energy...conference paper 2020

Wang, C. (author), Tindemans, Simon H. (author), Pan, K. (author), Palensky, P. (author)State estimation is of considerable significance for the power system operation and control. However, well-designed false data injection attacks can utilize blind spots in conventional residual-based bad data detection methods to manipulate measurements in a coordinated manner and thus affect the secure operation and economic dispatch of grids....conference paper 2020

(author), Gonzalez-Longatt, Francisco (author)This paper presents a comparative assessment of fast active power regulation (FAPR) control strategies implemented on megawatt-scale controllable electrolysers, with the goal of achieving enhanced frequency support during large active power imbalances that lead to major under-frequency deviations. The FAPR control strategies consist of three...conference paper 2020

Peyghami, S. (author), Blaabjerg, Frede (author), Rueda, José L. (author), Palensky, P. (author)Power electronic converters are one of failure sources in energy systems, and hence drivers of downtime costs in power systems. Different approaches can be employed for converter reliability enhancement including design/control for reliability methods, condition monitoring and fault diagnosis, and maintenance strategies. This paper proposes...conference paper 2020

Stecca, M. (author), Soeiro, Thiago B. (author), Ramirez Elizondo, L.M. (author), Bauer, P. (author), Palensky, P. (author)LCL filters are commonly adopted to attenuate the current harmonics produced by Pulse Width Modulation (PWM) Voltage Source Converters (VSC). Due to the nature of LCL filters, several combinations of L and C can deliver the attenuation required by the standards. The optimal configuration is generally evaluated, considering power density, costs,...conference paper 2020

Bhandia, R. (author), de Jesus Chavez, Jose (author), Cvetkovic, M. (author), Palensky, P. (author)Reliable power supply to the consumers is the key goal for power utilities. The two key reliability indices for power utilities are SAIDI and SAIFI. These indices indicate the average duration and frequency of supply interruptions for the consumer. A low value on these indices reflects a reliable and mostly uninterrupted power supply....conference paper 2020

Wang, C. (author), Pan, K. (author), Tindemans, Simon H. (author), Palensky, P. (author)The security of energy supply in a power grid critically depends on the ability to accurately estimate the state of the system. However, manipulated power flow measurements can potentially hide overloads and bypass the bad data detection scheme to interfere the validity of estimated states. In this paper, we use an autoencoder neural network to...conference paper 2020
