Aiming at the problems of imperfect dynamic verification of power grid security and stability control strategy and high test cost, a reliability test method of power grid security control system based on BP neural network and dynamic group simulation is proposed. Firstly, the fault simulation results of real-time digital simulation system (RTDS) software are taken as the data source, and the dynamic test data are obtained with the help of the existing dispatching data network, wireless virtual private network, global positioning system and other communication resources; Secondly, the important test items are selected through the minimum redundancy maximum correlation algorithm, and the test items are used to form a feature set, and then the BP neural network model is used to predict the test results. Finally, the dynamic remote test platform is tested by the dynamic whole group simulation of the security and stability control system. Compared with the traditional test methods, the proposed method reduces the test cost by more than 50%. Experimental results show that the proposed method can effectively complete the reliability test of power grid security control system based on dynamic group simulation, and reduce the test cost.

Unlike grid-connected microgrids, isolated microgrids are more susceptible to internal equipment capacity changes and external dispatching strategies, so it is necessary to analyze microgrid reliability from the perspective of capacity changes. Firstly, a time series model of equipment life process, a PV model with Beta distribution, a load model with time variability and stochasticity, and an energy storage model with operational constraints are studied. Secondly, the reliability index is used to characterize the system reliability level, and the power scheduling and load shedding strategy with minimum load shedding is proposed. Finally, the improved RBTS BUS6 F4 system is used as an example to deeply analyze the interaction mechanism of each device capacity on the reliability of the microgrid and to show the effectiveness of the proposed strategy.

The high temperature superconductor (HTS) CORC cable shows a great advantage on high-capacity power transmission. AC loss in HTS can considerably affect the efficiency of HTS cable during operation, which has to be calculated accurately in the cable design. The high capacity CORC cable often has dozens of HTS tape in parallel, which leads to a great challenge for the 3D electromagnetic modeling. This study is to conduct a fast AC loss calculation on the CORC cable by applying simplified 2D models, meanwhile, the results have enough accuracy for engineering applications. Two 2D simplified electromagnetic models based on H-formulation is developed for the AC loss calculation of CORC cable. Their accuracy is studied in detail by comparing with 3D models. The results show that air gap is the most important factor in the magnification loss calculation of CORC cable. In the simplified 2D models, the air gap should be the same with the physical one, which can significantly reduce the discrepancy. The 2D models are more accurate at high applied magnetic fields, and the discrepancy increased rapidly with decrease of applied fields. This study is useful for the fast and accurate AC loss calculation of high capacity HTS CORC cables.

With the randomness of charging electric vehicles (EV), it’s more challenging to formulate effective and reasonable electric vehicle scheduling strategies. Due to the price advantage of the power grid, a master-slave game model is developed, in which the grid is the game subject and the electric vehicle is the game subordinate. The particle swarm algorithm is used to obtain the optimal time-of-use electricity price strategy and grid dispatching strategy. Furthermore, the simulation experiment is designed with MATLAB. It is proved that the proposed model has an optimizing effect on the load curve and can reduce the peak-valley difference.

In order to analyze the local overheating of single phase three-legged transformer under AC/DC condition, the transient magnetic field and eddy current loss in the iron core of transformer are studied. This paper builds a coupling model of electric circuit and magnetic circuit considering nonlinearity of ferromagnetic materials and iron core topology. The distribution and variation of magnetic field and eddy current loss of single phase three-legged transformer are researched. The results show that the amplitudes of magnetic field and eddy current loss in the central leg are greater than those in two side legs without DC, and they grow nonlinearly as DC enlarges. The magnetic field amplitudes in the central leg grow faster than those in two side legs, while the eddy current loss amplitudes in two side legs grow faster than those in the central leg.

The current support mechanism for CSP plants in China does not take into account the impact of offering and operating strategies on the economic value of CSP plants, which plays a crucial role for the viability of the CSP plant investment. This paper proposed a bi-level stochastic programming model investigating the market behavior and economic benefits of CSP plants under typical renewable energy support mechanisms. Firstly, four typical support mechanisms were introduced, and a cost-benefit model for the life-cycle of CSP plants was constructed. Secondly, a coordinated optimization of the operation and bidding model for CSP plants was established to study the market behavior of CSP plants under different mechanisms. Finally, the impact of key mechanism parameters on the economic benefit of CSP plants was quantitatively analyzed. The results have a certain reference value for the promotion of CSP support mechanisms.

In this paper, a novel residential integrated demand response model is proposed, which enables residential consumers to participate in demand response programs not only by shifting appliances, but also through changing energy types they consumed. The integrated demand response is modeled from three levels, namely the interactions with utility grids, the flexibilities of power, cooling and heating demands and the optimal operation of smart energy hub. In order to demonstrate the effectives and advantages of integrated demand response, four contrastive cases are studied, and simulation results show that the integrated demand response can bring better economic and environmental benefits. Furthermore, a new evaluation index: electricity substitute ratio is also proposed to evaluate the integrated demand response capacity and potential.

Distribution terminal unit (DTU) is an indispensable device that monitors and controls other secondary-side devices in distribution network. With the large-scale integration of DTU into power system, limited numbers of maintenance engineers can hardly cope with the pressure brought about by the massive increment of DTU devices. Fault of DTU may lead to severe impact on normal operation of distribution network and power system. Therefore, researching DTU fault mechanisms and taking measures to lower fault incidence are crucial for ensuring the stable and safe operation of distribution network. In this paper, we proposed a FP-growth algorithm-based fault analysis method for DTU. Firstly, different possible factors that lead to DTU fault are analyzed, fault types are also introduced. Then the main idea of FP-growth algorithm is illustrated. Afterwards, a DTU fault analysis method based on FP-growth algorithm is put forward. Experiment is conducted on realistic DTU fault database to prove the practicality of this method.

As it is a severe challenge to accommodate the increasing new energy generation integrated to the power grid, electricity spot market can serve to address this issue by producing real-time time-of-use price signals and guiding consumers to adjust their electricity consumption behaviors. To resolve the dilemma of new energy consumption, this paper first designed a provincial bilateral electricity spot market, and put forward the trading mechanism considering both power plants and consumers. Then, a comparative analysis was conducted on the bilateral market clearing results and the unilateral market clearing results considering only power plants through case study. The results show that integrating consumers in the spot market can help to encourage them to consume new energy in an active manner. The bilateral electricity spot market proposed in this paper can provide a reference for improving the new energy consumption in regions with high new energy penetration.
