Wu, J. (author), Li, S. (author), Fu, A. (author), Cvetkovic, M. (author), Palensky, P. (author), Vasquez, Juan C. (author), Guerrero, Josep M. (author)

The increasing proportion of renewable energy introduces both long-term and short-term uncertainty to power systems, which restricts the implementation of energy management systems (EMSs) with high dependency on accurate prediction techniques. A hierarchical online EMS (HEMS) is proposed in this paper to economically operate the Hybrid...

Optimal energy system scheduling using a constraint-aware reinforcement learning algorithm

Shengren, H. (author), Vergara Barrios, P.P. (author), Salazar Duque, Edgar Mauricio (author), Palensky, P. (author)

The massive integration of renewable-based distributed energy resources (DERs) inherently increases the energy system’s complexity, especially when it comes to defining its operational schedule. Deep reinforcement learning (DRL) algorithms arise as a promising solution due to their data-driven and model-free features. However, current DRL...

A stochastic MPC framework for the control of pumping stations in polder systems with regard for uncertainty in inflow and hourly electricity prices

van der Heijden, T.J.T. (author), van de Giesen, N.C. (author), Palensky, P. (author), Abraham, E. (author)

The Netherlands is a low-lying country situated in the Rhine-Meuse delta. A significant portion of the Netherlands is located below sea level, making the proper management of local and national waterways essential. Polders are used to manage groundwater levels, drain excess rainwater, and store water during times of drought. These polders often...

Model predictive control and protection of MMC-based MTDC power systems

Shetgaonkar, A.D. (author), Liu, L. (author), Lekić, A. (author), Popov, M. (author), Palensky, P. (author)

Meshed offshore grids (MOGs) present a viable option for a reliable bulk power transmission topology. The station-level control of MOGs requires faster dynamics along with multiple objective functions, which is realized by the model predictive control (MPC). This paper provides control, and protection design for the Modular Multilevel...

The amount of power electronic interfaced generation (PEIG) is significantly proliferating in modern cyber-physical energy systems (CPESs). The limited capabilities (e.g. inertia, over-current) of PEIG, together with their location and technology-specific designed control systems, alter the dynamic properties of different types of stability...

Zero-sequence current suppression control for fault current damper based on model predictive control

Shetgaonkar, A.D. (author), Popov, M. (author), Palensky, P. (author), Lekić, A. (author)

In a multi-terminal direct current (MTdc) system based on a modular multilevel converter (MMC), high-speed and large interruption capability direct current circuit breakers (dc CBs) are required for dc fault interruption. However, commercializing these breakers is challenging, especially offshore, due to the large footprint of the surge...

Cyber Attacks on Power Grids: Causes and Propagation of Cascading Failures

Subramaniam Rajkumar, Vetrivel (author), Stefanov, Alexandru (author), Presekal, A. (author), Palensky, P. (author), Rueda, José L. (author)

Cascading effects in the power grid involve an uncontrolled, successive failure of elements. The root cause of such failures is the combined occurrence of multiple, statistically rare events that may result in a blackout. With increasing digitalisation, power systems are vulnerable to emergent cyber threats. Furthermore, such threats are not...
