In this paper, a computational framework for integrating wind power uncertainty and carbon tax in economic dispatch (ED) model is developed. The probability of stochastic wind power based on nonlinear wind power curve and Weibull distribution is included in the model. In order to solve the revised dispatch strategy, quantum-inspired particle swarm optimization (QPSO) is also adopted, which shows stronger...
This paper describes a multi-objective economic load dispatch (ELD) model to minimize the emission cost due to CO2 and N2O. The power system operation costs are minimized under transmission network constraints in ELD. This model will be transformed from single objective economic problem to multi-objective problem to combine both economic and emission dispatch. The model is implemented by Differential...
Air-fuel ratio control is a challenging control problem for port fuel injected and throttle body fuel injected spark ignition (SI) engines, since the dynamics of air manifold and fuel injection of the SI engines are highly nonlinear and often with unmodeled uncertainties and disturbance. This paper presents nonlinear control approaches for multi-input multi-output engine models, by developing adaptive...
The 300 MW CFB boiler has became the main type of electric power station boiler in china, which desulfate with the Limestone. Heat loss due to exhaust gas is the largest heat loss of boiler. Influencing factors of limestone desulfurization in CFB boiler on boiler thermal efficiency is described in the paper. New computation module for heat loss due to exhaust gas of CFB boiler is established. Heat...
The thermal efficiency and exergy efficiency of the 300 MW CFB boiler, which was firstly introduced into china, were calculated in the paper, so did the heat loss and exergy loss. Compared with the result of heat quantity method, the influence degree of the parameter, such as boiler operating load, exhaust gas temperature, excess air factor, air temperature.
