Dynamic Reactive Power Allocation Strategy for AC/DC System Based on Quantum Genetic Algorithm

ACM Cloud and Autonomic Computing Conference, 2020
With the fast increasing of new energy, the voltage stability control ability of the AC/DC hybrid grid is seriously insufficient and the voltage stability margin of the network is greatly reduced.

Quantitative analysis for dynamic asset allocation using the Chicago Fed National Activity Index

2023
Extensive literature has documented that asset classes returns vary depending on the economic regimes. The official business cycle dating performed by the NBER, and similar institutions is of little utility for real-time decision-making due to significant delays.

Optimal Allocation of Dynamic Var Sources for Reducing the Probability of Commutation Failure Occurrence in the Receiving-End Systems

IEEE Transactions on Power Delivery, 2019
Commutation failures (CFs) are usually triggered by the voltage dips caused by the faults in the receiving-end systems. To reduce the probability of CFs, counter measures to reduce the voltage dips should be implemented, among which adding dynamic var ...

An Index Policy for Dynamic Fading-Channel Allocation to Heterogeneous Mobile Users with Partial Observations

2008 Next Generation Internet Networks, 2008
This paper addresses a system model where multiple heterogeneous mobile users share a common wireless channel to a base station, extending work of Koole et al. (2001) which considered the corresponding homogeneous-user case. The channel's bandwidth is to be dynamically allocated to different users, based on partial information on their connectivity ...

Optimal allocation of dynamic VAR sources using zoning-based distributed optimization algorithm

, 2019
In this paper, a practical planning method to allocate dynamic VAR sources (DVSs) using the concept of voltage control areas (VCAs) is proposed to enhance short-term voltage stability of power systems.

The Indicators of Stock Market Macro Turning Points During Global Financial Crisis - Application to Dynamic Asset Allocation Investment Strategy Using Index and Exchange Traded Funds

SSRN Electronic Journal, 2012
The formulation of a winning investment strategy for the 2007-2009 Global Financial Crisis (GFC), also known as the 'Great Recession', essentially required making one key judgement that the global banking system would survive the Lehman Brothers collapse and identifying the two macro turning points: 2007 top and 2009 bottom of the market.

[Dynamic characteristics of leaf area index and allocation characters of ecological resources for different yielding spring maize populations].

Ying yong sheng tai xue bao = The journal of applied ecology, 2009
By using 3-year field experimental results and related meteorological observation data, the dynamic characteristics of leaf area index (LAI) and the allocation characters of ecological resources for different yielding spring maize (Zea Mays L.) population in Huadian of Jilin Province were studied.
