The increasing penetration of large-scale wind generation in power systems will challenge the power system inertia due to the reason that the converter based variable speed wind turbines have no contribution to the system inertia. Traditionally, a doubly fed induction generator (DFIG)-based wind power plant naturally does not provide frequency response because of the decoupling between the output power and the frequency. Moreover, DFIGs also lack power reserve margin because of the maxi mum power point tracking (MPPT) operation. In this paper, a virtual inertial control strategy of the DFIG based wind turbines called supplementary control loop for inertial response is investigated. When the system frequency is changing severely, the out put power of DFIG should respond to it rapidly through the virtual inertial controller at the same time. The rotor speeds of wind turbines can also be adjusted into this procedure. The inertial control methods proposed in this paper can supply controllable virtual inertia of DFIGs to the power system so that the system frequency stability can be strengthened through inertial control of wind turbines on the basis of damping torque analysis.

This paper presents a co-simulation model using MATLAB® toolboxes to illustrate an interaction between the communication system and the energy grid, coherent with the concept of smart grid that employs IEC 61850 communication standard. The MMS (Manufacturing Message Specification) protocol supported by IEC 61850, based on TCP/IP, is used for the vertical communication between the Supervisory and Data Acquisition (SCADA) system and Intelligent Electronic Devices (IEDs) embedding the local control of different parts of the smart grid. In this paper an IED supporting the power control of a photovoltaic (PV) plant connected to a low-voltage (LV) utility grid is considered. Communication system consisting of the transport layer and a router placed on the network layer is modeled as an event-driven system using SimEvents® toolbox and energy grid is modeled as a time-driven system using SimPowerSystems® toolbox. Co-simulation results are obtained by combining different communication scenarios and time-varying irradiance scenarios for the PV plant when this one is required to provide a certain power in response to a power reference received from SCADA over the communication network. The analysis aims at illustrating the impact that stochastic behavior and delays due to network communication have on the global system behavior.

Now the most used detecting method of MOA is the full current and resistive current on-line test. And the test method of existing instrument needs to get voltage signal from the second terminal of voltage transformer. This method is dangerous because an improper operation will cause a short-circuit in voltage transformer and even endanger personal safety. There fore, in order to solve the above problems, a new MOA arrester tester is developed in this paper. It uses a new way to obtain voltage phase signal and it gets voltage signal from the high voltage side of primary equipment and then sends it to the tester developed in this paper through wireless transmission to convert it to low voltage signal and then outputs to the original arrester tester to complete the resistance current testing. The device developed can finish arrester electrified test safely, accurately and conveniently. It can overcome the limitation of getting voltage signal from the second terminal of voltage transformer and the effect of interphase interference on test results can be effectively solved.

This paper presents a new scheme for distance local backup protection. In this scheme, two main points are included: The first is the distance component that could reliably detect all the faults occurring in protection area; the second is the pilot comparison strategy which is based on the results of distance components. The former employs the setting principle that could meet the requirement of sensitivity when the fault occurs at the end of line where the protection installed. The later could confirm the fault location through the comparison between results of distance components, and then the operating delay time would be flexibly determined depending on fault location. Regional pilot distance local backup protection could make sure that the speed and the selectivity would meet the requirement. Meanwhile, the cooperation between different kinds of protections would be simplified and the improved protection performance of the backup protection could be realized. Through the simulation sample, it can be seen that the protection scheme proposed in this paper could reliably judge the fault, and then the speed and the selectivity of the local backup protection would be guaranteed, meanwhile this scheme partially possesses the ability of fault tolerance.

Self-healing for smart distribution network which is based on Distribution Automation(DA) and Advanced Distribution Automation (ADA), is one of the key characters and core functions for smart distribution network to deal with the inside and outside threatens of the network as well as to increase system operation security and efficiency. In this paper, we focus on the modeling of self-healing control system for distribution network based on UML. Firstly, the background, application scenarios and requirements for self-healing control system of smart distribution network were analyzed. Then, the static and dynamic models of the control system were built based on UML. Three types of self-healing control are realized through four self-healing stages in three scenarios. Finally, based on the modeling results, the system architecture and key applications for the self-healing control system were implemented. The results in this paper are useful for investigation on the conceptions and key technologies, increasing the normalization and reusability of self-healing control system as well as guidance for real self-healing applications.

A reactive power evaluation model is proposed to estimate the available V2G capacity of reactive power provided by EV chargers during a day considering the travelling behaviors of EV users. Firstly, a generic EV charger model (GECM) is developed to describe the reactive power response characteristic of EV charger. Then, considering the travelling behaviors of EV users, a Monte Carlo simulation (MCS) method is implemented to build the reactive power evaluation model. Finally, the available reactive power from EV chargers is analyzed and compared under two different charging strategies (dumb charging and smart charging). Simulation results show that the reactive power evaluation model can determine the available reactive power capacity for V2G along a day, which can support the operation of the power system.

The output characteristics of the photovoltaic cell are a nonlinear and easily affected by external environment. The maximum power point tracking (MPPT) control is an effective method to improve the conversion efficiency of the photovoltaic system. In order to solve the problems of conventional fuzzy control algorithm, a new control strategy based on T-S fuzzy reasoning is proposed. This algorithm can avoid the oscillation near the maximum power point and reduce the energy loss with good dynamic and static performance. The model of the photovoltaic system is established and simulated by Matlab/Simulink. The simulation results show the effectiveness of the proposed control algorithm.

The output power of inverters should be precise equipartition in micro grid, because that is the basic conditions that the micro grid system works stably for a long time. This paper proposes a improved control strategy of inverters output power equipartition in micro grid based on virtual impedance method. Firstly, the output power equipartition conditions of inverters based on the droop control method are analyzed, and a measurement method of micro grid line impedance based on clock synchronization and Micro Grid Central Controller-(MGCC) coordinated control is presented. Secondly the output power ability of inverters, the active and reactive power decoupling ability, the system dynamic property and stability are served as the conditions of virtual impedance designed, therefore the optimal design method of virtual impedance values is proposed. The system simulation model was set up in MATLAB, and the simulation experiment results show that the proposed method has the effectiveness and practicability.

Traditional risk assessment methods focus on the power network side while ignoring the impacts of the information system. A risk assessment approach for power system based on a comprehensive fault probabilistic model is proposed. The risk factors of the information system are considered in the model. Overload and voltage violation risk indices are adopted. The risk indices thus gained can be used to help operators and the planners to monitor the system, and make a more credible plan. The correctness of the proposed approach is validated by IEEE-118 bus test system.
