Ambiguity‐Aware Receding‐Horizon Optimization of Wind‐Hybrid Energy Storage Systems Using Type‐3 Fuzzy Modeling for Multimarket Participation

open access: yesEnergy Science &Engineering, EarlyView.
A Type‐3 fuzzy ambiguity encoder converts rolling wind, price, reserve‐activation, and confidence features into central estimates and nested uncertainty bounds. These parameters are updated within a receding‐horizon MILP/MIQP that coordinates wind, battery, and supercapacitor capacity across day‐ahead and ancillary‐service markets.

Design of Microgrid Protection Schemes Using PSCAD/EMTDC and ETAP Programs

open access: yesEnergies, 2020
Steady-state, harmonics, and transient analysis of a power system by using a detailed simulation model is essential to microgrid operation before the installation of new power facilities, because the microgrid, which is a small-scale independent power ...

Frequency Shaping for Improving a Trade‐Off Between Control and Privacy Performance: Beyond Differential Privacy

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT In privacy protection of control systems, a trade‐off between control performance and privacy level is often pointed out. Our goal in this paper is to improve this trade‐off by shaping the frequency of noise added for privacy protection when the control objective is to track a reference signal, which is taken as a piece of information whose ...

Communication Assisted Protection Scheme Based on Artificial Neural Networks for Multi-Microgrid

open access: yesIEEE Access
Designing a properly coordinated protection scheme for a multi-microgrid is very challenging because of their distinct characteristics. A microgrid can be operated in a grid-connected mode through direct connection to utility or through another grid ...

Enhancing the protection of photovoltaic-based DC microgrids using circuit breaker operation sequence

open access: yesInternational Journal of Electrical Power & Energy Systems
The advancement of direct current (DC) microgrids is limited by insufficient operational experience, the inadequacy of suitable protective devices, and the absence of effective fault analysis methods.

Investigating the performance of non‐standard characteristics‐based overcurrent relays and their optimum coordination in distributed generators connected networks

open access: yesIET Generation, Transmission & Distribution, 2023
To handle the challenges attributed to the distributed generators, the protection system of distribution networks needs to be evolved. Recent protection schemes modify the standard characteristics of overcurrent relays, called non‐standard ...

A Person‐Environment Fit Framework for Measuring Multi‐Risk Community Resilience: 24 Indicators with Metrics and Vulnerability Thresholds

open access: yesSustainable Development, EarlyView.
ABSTRACT This study addresses a persistent challenge in community resilience research and practice: how to assess and build resilience when communities face multiple, interacting, and potentially unforeseen risks. It develops a relational framework for multi‐risk resilience based on Person–Environment (P–E) Fit Theory.
