Numerical Investigations of the Aerothermal Performance of Modern Turbine Blade Tip Geometries at Design and Off‐Design Conditions and Under Stationary and Moving Shroud

open access: yesHeat Transfer, EarlyView.
ABSTRACT High‐pressure turbine blade tips operate under extreme thermal stress, generating significant aerodynamic losses that must be continually optimized to improve engine efficiency and durability. This study uses computational fluid dynamics (CFD) to investigate the aerodynamic and thermal behavior of advanced turbine blade tip configurations ...

Resilience assessment for natural gas systems and electrical power systems without complete integration

open access: yesIET Generation, Transmission &Distribution, Volume 16, Issue 24, Page 4893-4913, December 2022., 2022
Abstract Considering the limited information sharing between natural gas systems (NGS) and electrical power systems (EPS), this paper proposes a distributed resilience assessment method for NGS and EPS. First, a coordinated restoration framework is presented for incompletely integrated energy systems, and the collaborative benefit redistribution ...

Optimal demand response programs selection using CNN‐LSTM algorithm with big data analysis of load curves

open access: yesIET Generation, Transmission &Distribution, Volume 16, Issue 24, Page 4980-5001, December 2022., 2022
Abstract One of the problems in implementing DRPs is the lack of sufficient understanding of consumers’ behaviour when implementing DRPs. This paper compares consumers’ load patterns annually by the improved Weighted Fuzzy Average (WFA) K‐means clustering method.

A dynamic equivalent aggregation method of wind turbine systems with a full‐scale power converter for electromagnetic transient simulations

open access: yesIET Renewable Power Generation, Volume 17, Issue 1, Page 36-51, 6 January 2023., 2023
A dynamic equivalent aggregation method is developed for wind turbine systems with full‐scale power converters to improve the electromagnetic transient simulation speed. A precision equivalence for the collecting network considering is introduced. A Louvain K‐means clustering algorithm is adopted to determine the optimal clustering result.
