The small-signal angle stability (SSAS) of a power system is determined by the property operation points. widely applied false data injection (FDI) cyber-attack, however, able to stealthily mislead optimal flow (OPF) and thus compromise points, leading damages SSAS margin. To provide insights for cyber defenders, this paper proposes investigates stealthy SSAS-oriented FDI cyber-attack focusing on two attacking purposes, i.e., margin cost, with higher priority former one. First, establishes...
The ability to withstand extreme disasters has a profound impact on the distribution network operation. This paper proposes novel optimal operation strategy for an active enhance system resilience.. objectives in proposed include, resilience, cost, and its pollutant emissions. According existence of uncontrollable distributed energy resources network, problem which takes uncertainty most into account, is this multi-objective optimization problem. Thus, it can be treated as min-max dual...
To accommodate unpredictable plug-and-play (PnP) of distributed generators (DGs) in droop controlled microgrids, this paper proposes a preventive–corrective stability constrained optimal power flow (SC-OPF). Firstly, considering that DG droops are restricted by load sharing, we introduce the battery energy storage system (BESS) with adjustable droops, which acts as new control resource. Secondly, propose bi-level optimization problem, where upper level ensures minimizing coordinated cost and...
The increasing penetration of distributed generators (DGs) makes further interconnection multiple energy carriers possible.

An optimal procedure including sizing, positioning, operation gas...
In order to better schedule distributed energy resources (DERs) improve the recovery ability of distribution network, optimal strategy is proposed in this study. The can be applied speed up process and reduce power shortage shedding loads network when a outage occurs. scheduling coefficient defined quantify rationality each resource. Based on index, study establishes an model, which consists three objectives. non‐dominated sorting genetic algorithm‐II search multi‐objective solution Then,...
The uncertain generations of renewable energy sources (RES) bring considerable challenges to voltage security in distribution networks. This paper proposes a conditional value at risk (CVaR)-averse distributionally robust chance constrained optimal power flow (CVaR-DRCC-OPF) which considers the regulation from perspective. CVaR violation is proposed act as an additional penalty term objective. Compared conventional chance-constrained OPF, CVaR-averse quantifies better, especially for...
To mitigate the stability issues in droopcontrolled isolated microgrids brought byaleatory renewable energy sources (RESs), which can be added at any given time, this paper proposes a two-stage robust coordination strategy to optimize operation of multiple flexible resources. In first stage, day-ahead unit commitment (UC) schedule microturbines(MTs) is formulated considering uncertainty RESs and loads. second an hourly power dispatch droop gains adjustment scheme for storage devices are...
Large Language Models (LLMs) represent a revolutionary advancement in the contemporary landscape of artificial general intelligence (AGI). As exemplified by ChatGPT, LLM-based applications necessitate minimal response latency and maximal throughput for inference serving. However, due to unpredictability LLM execution, first-come-first-serve (FCFS) scheduling policy employed current serving systems suffers from head-of-line (HoL) blocking issues long job times. In this paper, we propose new...
To figure out the stability issues brought by renewable energy sources (RES) with non-Gaussian uncertainties in isolated microgrids, this paper proposes a chance constrained optimal power flow (CC-SC-OPF) model. Firstly, we propose bi-level optimization problem, of which upper level aims to minimize expected generation cost without violating constraint; lower concerns about index given semi-definite program (SDP). Secondly, apply Gaussian mixture model (GMM) handle RES and introduce...
In this letter, we analytically investigate the sensitivity of stability index to its dependent variables in general power systems. Firstly, give a small-signal model, is defined as solution semidefinite program (SDP) based on related Lyapunov equation. case stability, also characterizes convergence rate system after disturbances. Then, by leveraging duality SDP, deduce an analytical formula any entries Jacobian matrix terms SDP primal and dual variables. Unlike traditional numerical...
Physical layer security is envisaged to provide secure wireless communications. So far there exist schemes that both achieve physical and maintain a reasonable level of link capacity. However, in all these schemes, capacity communication depends on the channel characteristics eavesdropping links. Thus, when packets are scheduled network with security, most critical task select an appropriate for new transmission such throughput quality services properly balanced. In this paper, packet...
A field trial of dynamic P2MP connections across two domains was successfully achieved in the ASON layer 3TNet testbed Yangtze River Delta, China for first time using web service mechanism.
To enhance the disaster response and recovery capability of distribution network when a power outage occurs, this paper proposes an optimal strategy under source load coordination mechanism. Since multiple renewable generations integrate in network, system flexibility resilience become considerable. In order to apply these features better improve ability, scheduling process should be optimized. Thus, concept coefficient obtain schedule network. Based on virtual coefficient, rationality index...
Because SONET/SDH technology which includes contiguous concatenation and virtual is used in GMPLS-Controlled Multi-services Transport Platform (MSTP) Network, it more complex when we consider the label assignment setting up a Label Switch Path (LSP). It very imperative to use method could limited labels effectively. In this paper, study structure of space different algorithm allocate labels, include MSTP Network. We proposed minimum Contiguous Labels Algorithm (min-CLA) solve problem using...
