With the revolutionary advances of integrated structural components in current automotive industry, aluminum alloy castings are in a rising demand. Aluminum alloy casting quality prediction in high responsiveness and low operational cost is crucial for structural components manufacturers. Therefore, casting machine manufacturers are urged to incorporate advanced quality prediction functions in the...Show More
At present, in high-voltage DC transmission systems, when the AC system on the inverter side malfunctions, if the DC control system responds improperly, it will lead to inverter commutation failure. Studying from the principle of extinguishing angle control, the advantages and disadvantages of measurement based and calculation based extinguishing angle control methods were compared. A composite co...Show More
A coordinated voltage regulation method based on model predictive control (MPC) is proposed in this paper for utilizing wind farms (WF) as black-start (BS) source to start up a thermal generating unit. The reactive power regulation devices with different dynamic response characteristics including wind turbine generators (WTGs), energy storage system (ESS), and static var generator (SVG) are coordi...Show More
In local power grid with high wind power penetration, using wind farm (WF) with energy storage system (ESS) as black-start (BS) source will significantly accelerate the restoration after blackout. For enabling WF to be a reliable BS source, an ESS sizing method based on asymmetric copula function is proposed, aiming mainly at smoothing WF output power during the process of starting up generator un...Show More
