For electromagnetic transient (EMT) simulation of a power system, a state-space-based approach needs to solve state-space EMT equations by using numerical integration methods, e.g., the Euler method, Runge-Kutta methods, and trapezoidal-rule method, at small time steps. The simulation can be slow on a power system having multiple generators. To speed up state-space-based EMT simulations, this paper proposes a Differential Transformation based semi-analytical method that repeatedly utilizes a high-order semi-analytical solution of the EMT equations at longer time steps. The proposed semi-analytical method is tested on the detailed EMT model of a four-generator two-area system. Simulation results show the significant potential of the proposed method to accelerate EMT simulations of power systems compared with traditional numerical methods.

Fault voltage and fault current have nonlinear and timing characteristics. To deeply study the importance of each characteristic variable for fault line selection and fault location of the distribution network, a fault line selection and fault location method based on a random forest (RF) algorithm was proposed. The location function is completed simultaneously based on line selection by improving the random forest sub-model. The proposed network amplifies the single label system to the multi-label task network, which facilitates the better expression of fault data features, improves the feature extraction ability of the network, and dramatically reduces the time of fault diagnosis. In this study, the fault data obtained by Simulink simulation is used as the training set, and the RF model is established based on the Scikit-Learn framework. The results show that this model has a high fault line selection rate and small location error. It can be used as an auxiliary means of distribution network fault diagnosis.

In common usage of three phase voltage source PWM rectifier in industrial transmission system, the control effect of DC bus voltage is related to the safety of the system. This paper presents a voltage sensorless control strategy in order to avoid the outer loop feedback distortion caused by DC voltage sensor fault. The idea of combining bus voltage observer with model error rolling optimization is proposed firstly. And a model predictive power control (MPC) method without bus voltage sensor is designed in this paper. For the PWM rectifier, based on MPC, a bus voltage observer combining sliding mode observer (SMO) and extended state observer (ESO) is designed to cope with the problem that the bus voltage is unobservable and the estimation accuracy is poor in special switch state using traditional sliding mode observer. Finally, by setting an adaptive threshold, the observer is used to realize the rapid reconstruction of the system in the case of sensor fault, so as to ensure the normal operation of the rectifier.

In order to charge the Li-ion battery efficiently and safely, a novel single-stage wireless battery charging system (WBCS) based on the semi-active rectifier (SAR) and the switch-controlled capacitor (SCC) in receiver side are proposed in this paper. SAR is used for implementing constant current (CC)-constant power (CP)-constant voltage (CV) charging profile and SCC is used to compensate the reactance caused by SAR so that the WBCS can maintain the tuning condition. To realize the CC-CP-CV charging and dynamic tuning simultaneously, real-time impedance calculation (RIC) method is introduced. Since the control strategies are based on fixed switching frequency and receiver-side regulation, wireless feedback communication is not required, leading to improved system reliability. A 900W prototype is built to verify the validity of the proposed WBCS. The experiment results show good performance and efficiency improvement for the WBCS in the whole charge process.

In order to optimize the heat dissipation capability of power devices attached to Printed circuit board (PCB), thermal vias are usually added to the PCB and heatsink are added on the back side. The idea of equal-area split vias filling is used to optimize the vias arrangement pattern, and the calculation formula of thermal resistance of PCB thermal vias unit is derived. The influence of the diameter of thermal vias, copper plating thickness, filling material and vias spacing on thermal resistance is studied by theoretical calculation formula. The thermal model is simulated using Icepak to compare the effects of the presence or absence of thermal vias on the PCB and the presence or absence of a heatsink on the temperature of the power devices. Finally, the correctness of the theoretical analysis is verified by comparing the theoretical analysis with the simulation results.

Large-scale wind power and photovoltaic combined with thermal power, energy storage and other equipment need to be send out, resulting in the increase in the cost of joint dispatching system and the obstruction of new energy consumption. In order to realize the economic efficiency of the combined dispatching of wind power and photovoltaic, thermal power and energy storage, this paper designs the operation framework of the combined dispatching of joint wind, photovoltaic, thermal and energy storage, aiming at the lowest comprehensive operation cost and the largest amount of new energy consumption. The paper establishes the dispatching model and selects the DC transmission channel from Xinjiang to Shandong for multi scenario analysis. By improving the flexibility of thermal power transformation technology, the comprehensive operation cost of the outgoing system was significantly reduced by 6.93%, and the energy abandonment rate was reduced by 9.30%. Under the dynamic adjustment of wind power and photovoltaic installed capacity, the utilization rate of new energy has a weak positive correlation with the increase of comprehensive operation cost.

In this paper, a decoupling control method is presented for single-phase cascaded H-bridge (CHB) rectifier, to eliminate the coupling effect of the capacitor voltage balancing controllers on the outer-loop voltage controller and inner-loop current controllers. Firstly, the coupling effect is analyzed according to the mathematical model of CHB rectifier. Then, the outer-loop reference voltage is redesigned to eliminate the coupling effect of the capacitor voltage balancing controllers on the outer-loop voltage controller. The active and reactive duty cycle components are designed to realize the decoupling of the voltage balancing control and the inner-loop current control, and the even distribution of the reactive powers among H-bridges. Finally, simulation results have verified the effectiveness of the proposed method.

To deal with the network limitation in a local energy trading market, the areas partitioning concept was proposed. This concept separates the network into source area and drain area and directly facilitates the rescheduling profile contribution in each area. The sharing factor based on the exceeded power, which caused the congestion, was initiated to reschedule the profile. Managing the exceeded power, the rebound effect was taken into account. The proposed rebound effect is the mechanism to manage the exceeded power in the direction of forward rebound and backward rebound. In addition, the price signal was also considered as a bonus price for the aggregators, who participate in the profile rescheduling.
