For the reliability evaluation of distribution network with wind power, the current application of different simulation methods have a common contradiction between accuracy and computational time. In this paper, a method for the reliability evaluation of distribution network based on Wasserstein distance multi-scene is presented. First, optimal quintile and its probability of wind power scenes are determined by probability distribution of wind speed and wind turbine power curve. Second, the feeder partition algorithm is applied to calculate the reliability indices of distribution network under different scenes. Finally, the total probability formula is used to calculate the reliability indices of distribution network with wind power. A comparison with the results of Monte Carlo simulation method shows that the proposed method is simple and efficient, having high accuracy and suitable for evaluating reliability of distribution network that encompasses wind power.

Order tracking analysis has been demonstrated to be suitable for wind turbine gearbox fault diagnosis, but in traditional way, a keyphasor signal is indispensable. In some real cases, due to harsh working environment and installation space limitation, it's hard to acquire this keyphasor signal. To overcome this problem, raw speed profile is used in this paper to synthesize the keyphasor, by assuming that the first pulse signal is at time zero, once the arriving time of the ith pulse is known, calculate the next pulse arrival time in two different ways, then minimizing the difference of these two results to get the next pulse arrival time. By assuming the shaft angular acceleration is constant between three consecutive pulses and using the synthesized keyphasor above, this paper successfully fulfill order tracking analysis on a United Stated MW-class wind turbine gearbox without keyphasor signal, which shows a very good engineering practicability.

Multi-type generators peaking problem has always been difficult to the researchers, since there are different generator models and complex constraints. In this paper, a decoupled multi-generator peaking model is proposed and used for control strategies. Also, the peaking control strategies are acquired through quantitative calculation and qualitative analysis. Quantitative calculation gives the output schedule for each unit or plant, while qualitative analysis analyzes the influence of different factors on peaking strategies, and the coordination method of various source types. Deep peaking of thermal units is taken into consideration and a bi-level optimization model is used to solve the thermal subsystem. The index of equivalent start-stop peaking capacity is defined, based on which the coordination method of multi-power peaking strategies is proposed.

In recent years, with rapid development of low voltage photovoltaic(PV) microgrid, control and protection technology associated with low-voltage microgrid has been the focus of research. Microgrid with its power can flow in both directions and fault current differs in the grid-connected mode and islanded mode, takes a great challenge to the traditional protection technology. To solve this problem, this paper proposes a new strategy to protect microgrid using the fault direction information, determines the switch's fault direction through the energy function, locates the external fault, common bus fault and feeder fault using fault direction information based on stratification searching thought. For the feeder fault location, this article creates direction information matrix, switch-branch matrix and branch-switch matrix, to achieve fast feeder fault location and action through the matrix operation. The Simulation results show that, the micro-grid protection strategies propose to achieve fast fault location and isolation, effectively protect the security and stability of low voltage photovoltaic microgrid.

Building an equivalent model of small and mediumsized hydropower generator group is a practical method carried out for dynamic analysis of water electricity grid. Excitation and governor system have prominent influences on the precision of the equivalent model. This paper presents a method to build a dynamic equivalent model of hydropower generator units containing excitation and governing system, the method uses traditional equivalent model of hydropower generator group which is based on homology method as the foundation, and considers the equivalence of excitation and governor system. It uses PLPF method to get the equivalent parameters of excitation system and weighted average method to get the equivalent parameters of prime mover and speed governor. Numerical examples show that deviation of the method in dynamic process is smaller, and it can improve the simulation accuracy. On this basis, further simulations are made to analyze the effect of excitation and governor system on dynamic characteristics.

Based on analyzing of the full-range wind power curtailment control (WPCC) operation characteristics, a novel WPCC (N-WPCC) strategy is proposed in this paper. The corresponding controller is presented, which consists of a rotor speed controller, a torque controller, a pitch angle and its compensation controller. Theoretical analysis and simulation results show that, through giving priority to the torque control than the pitch regulation compared with the traditional WPCC, N-WPCC can effectively decrease the pitch angle regulation frequency and amplitude, thus to extend its operating life, and can also improve the power generation to some extent because of taking the full advantage of the vast rotational inertia of turbines. In addition, output power and rotor speed are the control inputs for the proposed method, without the need of the wind speed.

The power grid in China has a series of problems of aged infrastructure, lack of resources and increased energy demand. The construction of smart grid is an important way to solve the above problems. The energy management and optimal adjustment in distributed power grid is the key for the system function realization, and several issues should be addressed: how to effectively manage the uncertainties of the intermittent power sources; how to manage the energy transferring equipment and diversities of the load varieties; and under different operational constraints, how to realize the high-level unification for multi-source distribution network economic operation and the reliability of power supply. The project will focus on these tasks based on load models considering the dual direction of the information between the energy suppliers and end users. It can reduce the energy generation cost, improve the energy quality, decrease the tariff, carbon emission and satisfy the user demands. The research will provide new infrastructure and technology support to smart grids with broad industrial application prospect.

This paper presents a new type of three-phase PWM rectifier with reactive power compensation function. The rectifier compensates reactive power based on its rated capacity. Under light and medium load, the rectifier has enough capacity to fulfill both reactive power compensation and PWM rectifier tasks. Thanks to the double-loop control and the sinusoidal-pulse-width-modulated (SPWM), the control system is able to stabilize the DC voltage and eliminate steady-state error. In addition to improvement of the power factor, the rectifier also has a unique advantage - improvement of equipment utilization. It is shown by analysis and simulations that the proposed rectifier offers an effective and practical solution to compensate the reactive power.

This paper presents a new impedance-based fault distance calculation formulation for power distribution systems. The majority of low- or medium- voltage distribution systems are characterized by having numerous branches, laterals and sub-laterals, highly unbalanced operation, and time varying load profile. All of these and other characteristics make most efficient approaches proposed for fault location in power distribution systems not applicable to distribution systems. The proposed method uses only measurements of voltage and current at the beginning of the analyzed feeder, and additional equipments such as, fault locators and monitoring devices are not needed to be installed in the distribution system. The apparent impedance is calculated by using the fundamental rms values of the measured voltage and current in this paper. This method is suitable to any kinds of fault and can be used to unbalanced power distribution systems, since it is derived in phase domain.
