Firstly, the limitation of using simplified model to design thermal generating unit controller is discussed. For the simplified model, the dynamic of the synchronous generator is neglected, and thus it is not valid in the emergency state of power systems. Secondly, the integral model of thermal generating unit is constructed, which consists of the models of boiler, turbine and synchronous generator...
Electric utility deregulation has made it possible for power producers and suppliers (PPSs) to enter the electricity market in Japan. PPSs are supposed to achieve 30-minute balancing control for stable supply of electrical power, in which energy demand and energy supply should be matched within thirty minutes. Meanwhile, load rejection and instantaneous voltage drop greatly affect turbine shafting,...
A novel maximum power point tracking (MPPT) strategy is presented in the paper. When wind speed varies, the wind turbine could obtain a big torque difference by adopting the novel strategy to achieve the aim of tracking the optimum turbine speed fleetly. The square wave permanent magnet synchronous generator (PMSG) is adopted in this paper for considering the characteristic of the diode rectifier-Boost...
