A new method to solve dynamic nonlinear constrained optimization problems (DNCOP) is proposed. First, the time (environment) variable period of DNCOP is divided
In 1994, we proposed transmission approach, the a novel fractional electricity frequency transmission system (FFTS), which uses lower frequency (50/3 Hz) to reduce
This article is concerned with the problem of observer-based passive control for descriptor systems with time delay. Sufficient conditions are first presented f
The anti-icing and de-icing methods of insulator strings are still under laboratory studies while many technologies are applied in operation to overhead conduct
The dissolved gas analysis is one of the most effective and convenient methods to diagnose the early discharge faults of transformers. When the fault involves t
A novel current limiting circuit breaker employs zero current switching method in cutting off DC current, which gives out a reverse impulsive current towards a
As a clean and renewable energy source, the small hydro plays a very important role in the power system. In China, the total installed capacity of small hydro h
Mid-long term hydro-thermal optimal dispatching plays an important role in mid-long term electric power and energy balance, and it also can bring significant ec
The breakdown strength, which is a fundamental parameter to characterize insulating materials, is always used as an important indicator to judge insulating prop
