Speech title：Advanced Model Predictive Control of Multiphase Machines
Abstract: The multiphase machines have been widely explored in industries and academia in the past years, since they can achieve the advantages of lower power rating per phase, lower torque pulsation and better fault tolerant capability. Thus, the multiphase machines are more preferred than the three-phase counterparts in high power and safety-critical applications, such as electric ship propulsion, elevator, wind power generation and so on. In addition, the model predictive control (MPC) has emerged as a competitive technique for the control of machine drives and power electronics in recent years. There are still many challenges imposed on the MPC when it is applied in conjunction with the multiphase machines. First, in the conventional MPC, the number of prediction vectors increases exponentially as the number of phase increases. Secondly, high amount of harmonic currents is introduced due to the small leakage impedance of the winding structure of asymmetrical six-phase machines. Thirdly, the parameter mismatch will result in prediction error, thus degrading the control performance. Advanced model predictive control strategies are desired to exploit the potential of multiphase machines.

Speech title：A State Reconfigurable Safe and Efficient Thermodynamic System for the Construction of New Power Systems
Abstract: As an increasingly bigger share of renewable energy power units are constructed, the load of thermal power units, like coal-fired power plants, must be frequently adjusted to extremely low load worldwide. An ultra-low load leads to a great thermal efficiency penalty for a thermal power unit, which greatly hinders the attempt to reduce carbon emission by employing more renewable energy power units. Based on fundamental research of thermodynamic theory and longtime retrofitting practices, a brand-new theory of state reconstruction and a modular design scheme of a thermodynamic system are introduced. On the ground of the state reconstruction theory, the thermal efficiency of a thermodynamic system could be sustained at a fixed value as high as that in rated condition. By adopting the modular design scheme, the high thermal efficiency on the rated could be realized discretely under a full load range. The above results break through the common sense that part-load operation of a thermal power unit inevitably results in an efficiency penalty, which might reduce the energy consumption a thermal power unit by 30-50g/kW∙h under part-load condition like 30%. A worldwide application of the state reconstruction theory and modular design scheme might reduce the energy consumption by ~200 million tec, and reduce the carbon emission by ~500 million tons, which is thought to be one of the final solutions for carbon neutrality.
