In view of the problem of power grid frequency fluctuation when load switching and renewable output power changed based on the Power electronic interface high respond speed character, a modified virtual inertia control control strategy has been applied to the output stage at Power Electronic Transformer(PET). The power support based on the virtual inertia is achieved and makes the energy internet flexible based on the construction of energy router. The control of MMC circuit at the input level in PET adopted virtual synchronous generator control strategy and the isolation level adopts traditional phase shift control. The advantage of proposed strategy is verified by the MATLAB/SIMULINK simulation.

With a global increase in electric vehicles (EV) the reliability, quality and performance of EVs is becoming increasingly important. High voltage direct current (HVDC) arc events in cables can lead to fires within EVs. Therefore, in this paper we investigate the failure modes mechanisms and effect analysis (FMMEA) of this safety critical issue. The onset of these failure modes can be multi-factorial so we created a statistical design of experiment to investigate the evolution and mitigation of these failures. Analysis of the arc characteristics collected in laboratory models has been decoupled and classified into time sub-domains. Utilising continuous wavelet transform (CWT) for capturing frequency features and minimizing the influence or erroneous signals. Verification testing was performed using a reference arc model in Simulink for comparative analysis of the experimental and simulated data. Mitigation of arcs via the incorporation of a fuse has been proven to provide sufficient circuit protection. Our results indicate that our methodology provides an accurate framework for cable arc classification and mitigation.

In this paper, the demand response is applied to the integrated energy system. Through the switching of transferrable load and heat storage device, a large number of loads are transferred to the period when wind power resources are abundant and conventional loads are relatively low, so as to absorb the forced wind abandonment, thus improving the utilization rate of wind power resources through transferrable load and heat storage device. Based on the further study of how to improve wind power absorption, this paper discussed the influence of wind power absorption system based on transferable load and heat storage devices to the traditional scheduling schemes. The objective function is established with the minimum forced wind abandonment volume and the minimum cost of the comprehensive operating system. The multi-objective genetic algorithm is used to solve the problem, and the optimal solution set can be obtained. Then the single objective optimization function is established by weighting method, and the optimal compromise solution and the final scheduling scheme is finally obtained. This paper takes a power grid operation system as simulation example, and shows that the dispatching scheme of using transferrable load and heat storage devices can greatly reduce the operating cost of the system and enhance the wind power absorption capacity of the system, compared with the traditional dispatching scheme.

With the increasing of DC load and the maturity of power electronics technology, AC/DC hybrid microgrid (HMG), as a new form of microgrid, has been widely concerned. The optimal dispatching method has become a key technology for the rapid development of AC/DC HMG. Based on the consensus algorithm, a distributed optimal dispatching method is proposed in this paper. Firstly, a convex optimization model about AC/DC HMG is established. Secondly, based on the multi-agent system, a distributed control framework is presented. The "Leader-Follow" consensus algorithm is the solution of optimization model, and the incremental cost of distributed generator (DG) and energy storage is selected as the consensus variable. The solution process is divided into two stages to meet AC and DC load respectively for reducing the energy conversion loss. Finally, the results of an example prove the feasibility of the presented distributed optimal dispatching method.

Edge computing terminals realize the decoupling between software and hardware, extend the functions of the terminals and meet the needs of diversified distribution service under Power Internet of Things. Workload modeling is the basis of computing resource configuration for edge computing terminals. Thus, this paper proposes a workload modeling method of edge computing terminals for distribution service. According to the timing logic of distribution service, the service is decomposed into several tasks and the sequential logic diagram is constructed. In the sequential logic diagram, directed edges are used to represent the dependency of the tasks. Combining the internal architecture of the edge computing terminals with the sequential logic diagram, the mathematical workload model is formulated. Based on the formulated models, a workload curve generation algorithm is proposed to obtain the computing resource demand of distribution service. Finally, the computing resources of the edge computing terminal are configured according to workload curve. Simulation results verify the effectiveness of the proposed model and method.

In recent years, environmental concerns and energy crisis have become serious issues. This has shifted much focus towards the solar energy which is green and renewable. In order to solve the shortcomings of low utilization, low automation and high cost of the traditional photovoltaic system, we propose an automatic tracking and maximum power output device for silicon photocell. The system is composed of solar automatic tracking device, maximum power point tracking (MPPT) system (controlled by STM32) and monitoring system based on Zigbee wireless. The solar automatic tracking device adopts four-quadrant photoelectric detection mode, realizes omni-directional and high-precision biaxial automatic tracking through logic circuit judgment, and makes maximum use of solar energy. The four-switch Buck-Boost circuit is used as the main circuit to realize wide range adjustment and synchronous rectifier control, which is combined with soft-switching technology to greatly improve the conversion efficiency of the system. ZigBee network monitoring system takes CC2530 as the node of transceiver. Results of testing showed, that solar automatic tracking device can track the solar trajectory with high precision and realize the maximum utilization rate of light intensity. The tracking accuracy of MPPT controller reached 99%, and the conversion efficiency also improved greatly, up to 98%. The monitoring system based on Zigbee wireless worked stably. In summary, the device effectively improves the utilization rate of solar energy. The simple structure and low cost make it of great practical value in engineering

In recent years, the application of Electric-Gas Integrated Energy System(EG-IES) has continued to develop, the coupling and connection between energy sources have become more and more close, and the interaction between power system and natural gas system has become complex. The change of power system network state will not only affect its own system, but also affect the natural gas system through coupling devices, which will cause huge economic loss when it is serious. This paper first analyzes the impact of voltage sag events in the power system on the electricity-gas integrated energy system, and then considers the natural gas system user economic loss assessment based on the process parameter immune time curve to provide a basis for subsequent voltage sag control methods. Finally, an electric-gas integrated energy system composed of IEEE14-node and 10-node natural gas systems is selected as an example to verify the correctness and effectiveness of the evaluation method.
