A Paradox Perspective on Business Model Innovation in Sustainability‐Oriented Industries: A Longitudinal Case Study in the Energy Sector

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines how Business Model Innovation (BMI) unfolds in sustainability‐oriented industries, where institutional complexity, technological interdependence, and environmental imperatives generate persistent sustainability‐related paradoxical tensions.

Insight into microgrid protection

IEEE PES Innovative Smart Grid Technologies, Europe, 2014
Microgrids consist of a combination of generation resources and load, forming an electrically sustainable entity. Although the feeder configuration, including location of circuit breakers or switches, and selection of protective devices can change from one microgrid to another, some characteristics like size of microgrid and behavior of sources feeding

Transition Metal Compounds as Thermochromic Materials: Classification, Properties, Limitations, and Applications

EcoEnergy, EarlyView.
This review systematically examines how different transition metal compounds—such as binary and multinary metal oxides, halides, sulfides, and salts—exhibit thermochromism based on the d‐electron configurations of their transition metal cations. It focuses on three main mechanisms of thermochromism: phase transition, charge transfer, and bandgap change.

An Active Protection Scheme for Islanded Microgrids [PDF]

15th International Conference on Developments in Power System Protection (DPSP 2020), 2020
The paper proposes a relatively simple active protection strategy incorporating controllers of the inverter for islanded microgrids dominated by inverter based distributed generators (IBDGs) that can overcome well-understood shortcomings in traditional overcurrent protection schemes applied to weak islanded systems.

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

Energy 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.

A black-box dynamic equivalent model for microgrids using measurement data [PDF]

, 2014
A dynamic equivalent black-box model, based on Prony analysis is presented. The proposed model is suitable for dynamic studies of microgrids, considering changes in the active and reactive powers, bus voltages, currents and frequency. The developed model

A Comprehensive Review of Fault‐Current Limiter Technologies for Smart and Resilient Power Systems

Energy Science &Engineering, EarlyView.
This review compares superconducting, solid‐state, and hybrid fault‐current limiters (FCLs) for modern alternating current, direct current, and hybrid grids. It shows that optimal FCL selection depends on fault characteristics, network configuration, voltage level, protection coordination, and resilience requirements rather than on a universally ...

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

International 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 ...
