Study on Emergency Load Shedding of Hybrid AC/DC Receiving-End Power Grid with Stochastic, Static Characteristics-Dependent Load Model

Energies, 2019
When large-capacity HVDC (high voltage direct current) transmission line blocking occurs in a hybrid AC/DC (alternating current/direct current) power grid, the receiving-end system will encounter a huge power imbalance, which will lead to a frequency ...

Power-Supply Systems Reliability Control [PDF]

EAI Endorsed Transactions on Energy Web, 2018
System reliability control is proposed to maintain through the usage of the operating time between the system components' failure. Usually, trouble-free (reliability) is assessed considering component failures. Almost all the system probabilistic parameters were determined via the component failures.

Molecular pyrolysis process and gas production characteristics of 3‐element mixed insulation oil under thermal fault

High Voltage, 2022
Mixed insulation oil is considered as a desired substitute for traditional mineral oil. A novel 3‐element mixed insulation oil has been developed in our previous works, whose parameters satisfy the mineral oil standard (IEC 60296:2012).
