This paper proposes a new pilot protection method for ultra-high voltage (UHV) transmission line, which is based on the characteristics of the average value of the fault component current. Theoretic analysis shows for an internal fault, the signs of the average values of the fault component current detected by relays on both ends of the line are identical, while they are opposite for an external fault. Through comparing the signs of the average values detected by two relays on both ends of the line, an internal fault can be distinguished from an external fault. Using PSCAD software, a 1000 kV transmission line model was constructed, and extensive simulations were performed. The simulation results indicate the validity and feasibility of the proposed protection method.

With the development of UHVDC technology, the capacity of power transmission is getting increasingly bigger, which will generate a great impact on the receiving power system. This paper proposed a novel separating pole connection (SPC) mode to address this issue. Firstly, the paper introduced the configuration concept of SPC and presented the definition of short circuit ratio for separating pole connection mode (SPCSCR). And the abilities of power transmission related with SPCSCRs under different connection modes were analyzed. Secondly, the overall control strategies for UHVDC SPC mode were studied and suggested independent control systems for two poles respectively. Finally, the dynamic behavior of SPC mode was studied by a case of UHVDC transmission using PSCAD/EMTDC, and the results validated the advantages of this structure, which has great superiority in stable operation and flexible power transmission.

Dynamic thermal rating (DTR) is an effective technique to improve the ampacity of overhead power transmission lines based on the monitoring of real-time environmental conditions. With DTR technology being introduced, the thermal rating of transmission line is no longer constant but time-dependent. To fully utilize the transfer capability of transmission lines, it is necessary to provide operators with probabilistic forecasting information of DTR to make dispatch decision. In this paper, a new probabilistic forecast method based on the quantile regression analysis theory is proposed to realize the probabilistic prediction of DTR. The weather parameters which have significant influence on the real-time ampacity and historical line ratings are embedded in the quantile regression prediction model. The proposed method can not only give the point prediction and interval prediction result, but also can provide the forecasting results of probability distribution function. Finally, the validity of the proposed method is illustrated by case studies.

A seamless switching control strategy for multi-terminal flexible HVDC system, presented in this paper, can maintain DC voltage of system stable and ensure a reasonable power allocation of converter stations. This strategy improves active channels of the outer loop, which enhances flexibility and selectivity of control by setting droop control mode cover fixed DC voltage control mode and constant active power control mode. Only by changing the control mode selection coefficients can realize switching of three kinds of control mode and self-switching of droop control mode, which reduces the fluctuation and shock generated by using the switching hardware and improves the transient stability of the system. Finally, a RT-lab simulation model of the five-terminal flexible HVDC transmission system is built to verify the effectiveness of the proposed control strategy, and the seamless switching among the control modes is realized.

Reactive power optimization is generally used to design an optimal profile of voltage and reactive power of power systems in steady state for deterministic sets of demand load and generation values, and it is a significant procedure in voltage control. However, the input data of power system is actually uncertain in practice, which makes reactive power optimization an uncertain nonlinear programming, and it is not solved properly at present. To address this problem, the input data is considered as interval and reactive power optimization incorporating interval uncertainties is proposed to model this problem. In order to solve this model, genetic algorithm is employed as the solution algorithm, where reliable power flow calculation is used to judge the constraints of the model. The IEEE14 system is tested and analyzed to demonstrate the effectiveness of the proposed method, especially in comparison to previously proposed chance constrained programming.

The penetration of distributed generations (DGs) will grow gradually in future distribution system where islanded operation of microgrid (MG) helps to improve local and overall reliability. However, the microgrid load point outage time and outage frequency are affected directly by island load control strategy (load shedding and restoration strategy) which is not wholly considered in existing reliability evaluation methods. This paper proposes two improved strategies based on usual load control strategy considering fluctuation and correlation characteristics of renewable distributed generations power output and load demand. Applying sequential Monte Carlo simulation (SMCS) method,this paper analyzes the impacts of load control strategy on microgrid reliability quantitatively. Simulation results show that island load control strategy has important effect on microgrid reliability ,and the proposed strategies are more reasonable which can further improve microgrid reliability.

A novel three-phase series-connected modular multilevel converter in T configuration (TSC-MMC) for high voltage direct current transmission system is presented. The paper studies the dynamic mathematical model and the control scheme based on the proposed topology. Compared to conventional MMC, the number of IGBTs in TSC-MMC is reduced when withstanding the same dc voltage, which effectively decreases the system cost. Due to the series connection, no circulating currents exist in TSC-MMC. When the auxiliary arms on the dc side consist of full-bridge sub-modules (FBSMs), fault currents can be eliminated by blocking the cascaded FBSMs when dc fault occurs, without using circuit breakers. Moreover, an optimization of reactive power distribution between the main arms and the auxiliary arms is presented to improve the system performance. The simulation results obtained in MATLAB/Simulink are provided to verify the new topology as well as the proposed control strategies.

The composition and analysis of the loss of flexible HVDC transmission system based on modular multilevel converter (MMC) is a great challenge for engineering application. An energy efficiency measurement scheme for flexible HVDC transmission system is proposed in this paper. Firstly, the power losses caused by each energy consumption equipment in flexible HVDC transmission system is analyzed quantitatively. It can be seen that the most of the losses come from the converter valve and connection transformer. After considering energy consumption rate, economy, harmonic influence, the choice of relevant energy efficiency measurement points is then determined. Moreover, the accuracy and the error consistency of measuring device are analyzed according to the error transfer theory. Finally, the feasibility of the scheme will be proved by a typical flexible HVDC transmission system. This scheme provides guidance for the energy efficiency analysis of flexible HVDC transmission system, which is useful for the future applications.

Power synchronization control is a new control strategy of VSC-HVDC for connecting a weak power system. This paper reveals that VSC station used power synchronization control normally is dynamically “coupled” with the power system so that the parameters of reactive loop of the VSC-HVDC will make an impact on dynamic interactions and presents the theoretical analysis to explore existence of more strong dynamic interactions than vector control between the VSC-HVDC and power system under same conditions. Dynamic interactions may occur to affect the damping of the electromechanical oscillation mode which is estimated by participation factors in this paper. At the end of the paper, an example power system is presented to demonstrate and validate the theoretical analysis and associated conclusions are made.

Multi-terminal HVDC (MTDC) technology using voltage source converter (VSC) is a good option for wind power integration. Compared with point to point DC connection, MTDC provide better controllability based on different control strategies. In this paper, proportional-integral (PI) controllers with tuned PI parameters are designed to coordinate DC flow among the DC grid with good dynamic performance. In order to overcome the disadvantages of the conventional PI control, a simple adaptive PI control strategy is proposed based on the system transfer function. Case studies were conducted with PowerFactory.
