Power system emergency control is generally regarded as the last safety net for grid security and resiliency. Existing schemes are usually designed offline based on either conceived "worst" case scenario or a few typical operation scenarios. These facing significant adaptiveness robustness issues increasing uncertainties variations occur in modern electrical grids. To address these challenges, this paper developed novel adaptive using deep reinforcement learning (DRL) by leveraging...
Recently, orthogonal frequency division multiplexing (OFDM) with index modulation (OFDM-IM) was proposed. By selecting a fixed number of subcarriers as active to carry constellation symbols, the indices these may additional bits information. In this paper, we propose two generalization schemes OFDM-IM, named OFDM generalized 1 (OFDM-GIM1) and OFDM-GIM2, respectively. OFDM-GIM1, in an subblock is no longer fixed. Dependent on input binary string, different numbers are assigned symbols....
The introduction of the microprocessor-based numerical relay in 1980s resulted multifunctional, multidimensional, communications-enabled complex protection systems for zone and system protection. increasing capabilities this technology created new unintended challenges: 1) complexity has increased selecting coordinated settings is a challenge leading to occasional miscoordination; 2) functions still rely on small number measurements (typically three voltages currents) limiting ability...
With the ever increasing penetration of renewable energy, smart loads, energy storage, and new market behavior, today's power grid becomes more dynamic stochastic, which may invalidate traditional study assumptions pose great operational challenges. Thus, it is critical importance to maintain good-quality models for secure economic planning real-time operation. Following 1996 Western Systems Coordinating Council system blackout, North American Electric Reliability Corporation (NERC)...

Series compensated transmission lines challenge legacy protection schemes. In this paper, a dynamic state estimation based (EBP) method is proposed to address these challenges. The requires GPS synchronized measurements at both ends of the line and high-fidelity model zone. paper presents zone its impact on performance scheme. Numerical simulations show that can correctly identify faults, independently position type. also compares versus functions such as distance differential protection....
Accurate fault locating minimises labour and outage time. Efforts to increase the accuracy of methods are on‐going. In this study, a dynamic state estimation‐based (EBFL) method is proposed. Best implementation requires GPS synchronised sample value measurements at both ends line. The estimator operates on sampled values using detailed model line, which includes location as state. Specifically, line represented multi‐section transmission model, inclusive phase conductor type size, shield...
The promise of the smart grid entails more interactions between transmission and distribution networks, there is an immediate need for tools to provide comprehensive modelling simulation required integrate operations at both levels. Existing electromagnetic transient simulators can perform simulations with integration systems, but computational burden high large‐scale system analysis. For stability analysis, currently are only separate simulating dynamics systems. In this study, authors...
This paper proposes a new fault location method for transmission lines in MMC-HVDC grids based on dynamic state estimation (DSE) and gradient descent. The only requires short data window of 5 ms after the occurrence therefore is applicable with high-speed tripping techniques. first builds high-fidelity linear model DC line, which accurately describes physical laws line during fault. Afterwards, consistency between measurements evaluated through DSE algorithm. Finally, actual corresponds to...
Accurate pin-pointing of faults on transmission lines minimizes outage time, labor, and costs. This letter proposes a simple yet effective ensemble Kalman filter (EnKF) approach to accurately locating the within half-cycle time. The is easy implement does not require foreknowledge either fault type or an approximate guess location. Extensive results validate effectiveness accuracy EnKF-based location approach.
High-voltage direct current (HVDC) transmission lines are increasingly being installed in power systems around the world, and this trend is expected to continue with advancements electronics technology. These also bringing multiterminal (MTDC) closer practical application. In addition, continued deployment of phasor measurement units makes dynamic information about a large system readily available for highly controllable components, such as HVDC lines. All these trends have increased appeal...
Integration of new radio technologies to legacy ones has always been an important feature in any wireless communication generation shift and it is envisioned that for the transition 5G this will be even more critical.
