Techno‐Economic Assessment of Large‐Scale Renewable Energy Systems: A Case Study in the Gulf Cooperation Council

Energy Science &Engineering, EarlyView.
A consistent 3 GW hybrid solar–wind configuration was assessed across five GCC locations, revealing substantial regional differences in energy yield and economic performance. Saudi Arabia and Oman achieved the highest generation and lowest LCOE, while the systems delivered substantial CO2 emission reductions across the region.

Identification and Stabilization of Critical Clusters in Inverter-Based Microgrids

CoRR, 2020
A new method for stability assessment of inverter-based microgrids is presented in this paper. It leverages the notion of critical clusters -- a localized group of inverters with parameters having the highest impact on the system stability. The spectrum of the weighted network admittance matrix is proposed to decompose a system into clusters and rank ...

Distributed consensus-based control of multiple DC-microgrids clusters [PDF]

IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society, 2014
This paper presents consensus-based distributed control strategies for voltage regulation and power flow control of dc microgrid (MG) clusters. In the proposed strategy, primary level of control is used to regulate the common bus voltageinside each MG locally.

Distinct Solvent Effects on Dispersibility and Photoinduced Hydrogen Release of Hydrogen Boride Sheets

Small, EarlyView.
Hydrogen boride (HB) sheets exhibit strongly solvent‐dependent dispersion and photoinduced hydrogen release. HB‐sheet dispersibility depends on solvent‐dependent interactions, whereas hydrogen release is more strongly associated with the hydrogen‐bonding character of the solvent.

Control of Microgrid Cluster Using Raspberry Pi

2023 IEEE International Conference on Energy Technologies for Future Grids (ETFG), 2023
Currently, microgrid clusters (MGC) are being increasingly used owing to their benefits and human needs. MGs can be composed of power generation, consumption, and storage elements. They permit the combination of DC and AC technologies, even for a single microgrid (MG).
