In order to solve the problem of large-scale and multi type distributed generation, energy storage and electric vehicle flexible load access, a multi energy complementary microgrid solution based on power router is proposed. This paper puts forward three energy supply schemes based on power router to realize the flexible access and efficient management and control of distributed generation, energy storage, flexible load and other units of different voltage levels. Secondly, a comprehensive evaluation index system based on reliability, economy, high quality and environmental protection is constructed. The weights of each element are determined by the subjective and objective weighting method of AHP-EWM method, and the accuracy of weight is improved by using combination weighting method. Finally, the comprehensive evaluation is carried out through the gray correlation analysis method. Taking data center station, electric vehicle charging station and AC load power supply in substation as examples, three alternative power supply schemes are systematically evaluated, and the results show that the evaluation method is effective.

With the continuous development of power electronic technology, the distributed renewable energy generation connected to the distribution network is increasing, and the flexible load such as electric vehicles is also increasing. As a multi-port power electronic equipment, power router (PR) can accept power electronic power supply and load, and be used to build a flexible power distribution system with high power electronic source and load penetration. First, based on VSC power flow calculation steady-state model, this paper proposes a steady-state model of PR; Second, according to the type of bus at both ends of the line and the type of line, the line structure in the AC/DC hybrid power distribution system based on PRs is divided into 8 categories. Power balance equations, supplementary nodes and equations at node i under various structures are analyzed, and based on the classification of the line structure, the node equations of PR nodes and non-PR nodes are analyzed. Finally, the operating constraints of PR and VSC are introduced, with the goal of minimizing the total power generation cost of the system, and the optimal power flow calculation model for the AC-DC hybrid distribution network based on PRs is constructed. Some nodes are replaced with PR of IEEE14 system as a test system for test verification.

Synchronous thermal analyzer, tube furnace flue gas analyzer and gas chromatography-mass spectrometry (GC-MS) are used to study the combustion simulation experiment of control cable in substation. In the experiment, different gas atmosphere and heating rates are selected to simulate the combustion conditions in different scenarios of actual fire. The results show: in term of pyrolysis characteristic, the main components of the control cable (outer sheath, inner sheath and insulating layer) have one or two weightlessness stages during pyrolysis in nitrogen atmosphere, and two or three weightlessness stages during pyrolysis in air atmosphere. Due to the existence of oxidation reaction, the mass fraction of the control cable pyrolysis residues in nitrogen atmosphere is generally higher than that in air atmosphere; In term of gas product, the inorganic products mainly include CO, CO2, HCl and H2O. Under the condition of sufficient oxygen supply, CO2 and CO are the majority. The yield of CO2 is usually more than 10 times that of CO, and the yield of HCl is only 20% that of CO. Organic products mainly include benzene series, and its yield ranges from 0.0001 to 0.04g/g. According to the analysis of pyrolysis gas products’ composition, the pyrolysis gas products of control cables have certain toxicity and corrosiveness, and have certain risks to the safety of personnel and environment under fire.

The sealing performance of transformer has important influence on its safe operation. However, sealing of the equipment is related to the pressure that applied. In this paper, gas content test of mineral oil under different pressures were conducted to simulate the situation under different sealing degree, and the two-parameter Weibull distribution was used to analysis the data. Composite model of mineral oil and air have been built and balanced under different pressures. The amount of gas molecules in mineral oil and the interaction between gas molecules and mineral oil were calculated. The test results show that the gas content of mineral oil increases gradually with the increase of pressure. When the pressure increased from 6.3kPa to 101.3kPa, the gas content in mineral oil with a probability of 63.2 % increased from 4.26 % to 8.99 %. When the pressure increased by 16.08 times, the gas content in mineral oil increased by 2.11 times. The repeatability of the three measurements was good. The simulation results show that with the increase of pressure, the interaction energy between mineral oil and gas molecules increases gradually, and the number of gas molecules entering mineral oil increases. When the pressure increases from 10.1kPa to 1013kPa, the interaction energy between mineral oil and gas molecules increases from 68.61 kcal/mol to 104.98 kcal/mol. The number of gas molecules entering the mineral oil increased from 110 to 161. The experimental results are in good agreement with the simulation results.

The operation duration of isolated island formed after fault is an important indicator of the operation ability. In this paper, a novel bi-level mixed-integer nonlinear model is proposed to evaluate the maximum operation duration of isolated island with fully consideration of the uncertainties of the wind turbines (WTs), the photovoltaics (PVs) and the load. Besides, risk limitation and the control strategies of distributed generators (DGs) and distributed energy resources (DERs) are also considered. The modified IEEE 33-bus power system with a certain penetration of WTs and PVs is employed to validate the proposed method. The simulation results indicate that the proposed model can evaluate the system’s operation duration more realistic, and improve the credibility of the evaluation results.

Integrated energy system has the ability of flexible regulation, which can effectively improve the utilization of primary energy and promote the consumption of renewable energy. In this paper, an integrated energy system composed of CHP, heat pump, wind power and thermoelectric flexible load is studied. In order to make full use of the dispatching value of thermoelectric flexible load in integrated energy system, a thermoelectric flexible load model was established to participate in demand response in integrated energy system. By fully considering the different regulating characteristics between the heat demand response and the electric demand response, the price type electric demand response is included in the day ahead dispatching model, and the target of this model is the minimum cost of system operation. The incentive heat demand response is adjusted to the intraday dispatching model, and the deviation assessment cost is taken as the objective, thus a two-stage optimization model of integrated energy system is established. The simulation results show that the proposed model can give full play to the dispatching value of different demand responses, improve the system flexibility, effectively reduce wind curtailment, power purchase and the fluctuation of wind power. Thus, the overall efficiency of the integrated energy system is improved. This model also promotes environmental protection and improves economic operation of the integrated energy system, and can provide reference for the optimization of the integrated energy system.
