Research on Automatic Generation Control with Wind Power Participation Based on Predictive Optimal 2-Degree-of-Freedom PID Strategy for Multi-area Interconnected Power System

open access: yesEnergies, 2018
High penetration of wind power in the modern power system renders traditional automatic generation control (AGC) methods more challenging, due to the uncertainty of the external environment, less reserve power, and small inertia constant of the power ...

Investigation of insulation properties and synergistic effects in CF3I/N2 gas mixtures using the Boltzmann equation [PDF]

open access: yesAIP Advances
CF3I is regarded as a highly promising substitute for SF6; however, due to its high boiling point, buffer gases such as N2 must be blended. To evaluate the feasibility of replacing SF6 and its mixtures with CF3I/N2, a comparative analysis was conducted ...

Thermodynamic analysis of a novel fossil-fuel–free energy storage system with a trans-critical carbon dioxide cycle and heat pump [PDF]

open access: yes, 2020
This paper presents and analyzes a novel fossil-fuel–free trans-critical energy storage system that uses CO2 as the working fluid in a closed loop shuttled between two saline aquifers or caverns at different depths: one a low-pressure reservoir and the ...

MaimAir: A flexible and modular energy storage system for tomorrow energy banks [PDF]

open access: yes, 2016
We considered a novel energy storage system based on the compression of air through pumped water. Differently from CAES on trial, the proposed indirect compression leaves the opportunity to choose the kind of compression from adiabatic to isothermal. The
