A bi-level generation-network-energy storage coordination programming model of an active distribution network (ADN) considering the uncertainty of hydro and photovoltaic (PV) is proposed. Take advantage of the flexible output characteristics of hydropower generators to optimize the installation capacity and siting of distributed PV from the perspective of optimal operation of hydro-PV complementary systems. The upper level of the model is to minimize the comprehensive cost to make decisions on locating and sizing distributed generations (DG) and energy storage. The lower level, with annual operation and maintenance costs and fast voltage stability as the objectives. The economic dispatching of the ADN is realized by taking into account the output of DGs, hydro-PV complementary systems, and the charging and discharging of energy storage. Two-level PSO with a local search algorithm is used to solve this model in a simplified 51-bus distribution network in a region of Yunnan. The simulation results show that the proposed method can effectively reduce the investment cost and operation cost of the ADN, and improve the current problem of low voltage quality under the Yunnan distribution network.

This paper is to present modeling and control of a designed delta planar robotic manipulator. We address the system modeling issue from mathematical models to physical models in Simulink. Inspired by the path following control problem as studied in [1], we show a point-to-point regulation design. Particularly, we embed a high-gain observer-based regulator to do so. The proposed result is demonstrated by numerical simulations, including a test based on a physical model relating to a real designed delta robot.

In order to prevent the main transformer, high resistors and other large oil-filled electrical equipment from spraying and leaking oil and causing environmental pollution, so special accident oil pools are set up in substations for transformer oil treatment. Therefore, it is also important to strengthen the monitoring of the level of the transformer accident oil pool. In this project, a liquid level monitoring and alarm system is designed on the basis of the transformer accident oil pool to realize the relevant functions.

The insulators in operation are exposed to the air. Under the conditions of humid air (such as fog and drizzle), when they are seriously polluted, and the external insulation configuration is insufficient, the insulators will have pollution flashover, leading to a power failure of the line. UHV transmission lines feature large energy transmission and long distance. Once pollution flashover accident occurs, it will seriously threaten the stability of the power supply system [1]. Therefore, it is of great significance to determine the design of external insulation configuration of ultra high voltage project scientifically and economically. In this paper, the climatic environment, pollution source distribution and operating experience of nearby projects along the Sichuan-Chongqing transmission line are studied and analyzed. The AC pollution level is proposed. Through the research and analysis of insulator pollution test data of transmission lines along the Sichuan-Chongqing line, the key pollution accumulation characteristics of insulators in different environmental areas along the project, namely, the pollution ratio of top and bottom surface areas, are determined. The pollution flashover tests under different pollution conditions of top and bottom surface areas were carried out, and related pollution coefficients were obtained. According to the results of artificial pollution flashover voltage test of insulators, combined with the equivalent salt deposit density characteristics in Sichuan and Chongqing, the external insulation configuration under typical pollution conditions along the Sichuan-Chongqing UHV line was recommended.

Voltage support strategies in grid-connected inverters have been extensively studied, yet they usually induce frequent mode switching and power imbalance between DC and AC sides under different voltage sag depths. To address those issues, this paper proposes a voltage support strategy based on active and reactive currents coordinated injection. The AC voltage control loop with anti-windup and adjustable reactive current limit is complemented in the current control. Meanwhile the operating conditions are divided according to the maximum available active current reference and the optimal active current reference, which are used to adjust the limits of active and reactive currents. This strategy avoids frequent mode switching and achieves better voltage support under different voltage sag depths. Simulation results verify the effectiveness of the proposed strategy.

Optimal power flow with small-signal stability constraint has attracted extensive attention because it can consider both small-signal stability and economy. However, the appropriate small-signal stability constraint threshold is not known in advance. In this paper, firstly, a multi-objective optimal power flow model is constructed with the objectives of small-signal stability and generation cost, and considering the constraints and limitations of system operation. Secondly, to obtain the Pareto optimal set, multi-objective particle swarm optimization is used to solve the proposed model. Finally, a fuzzy membership function is introduced to select the best compromise solution objectively and fairly. Simulation results for an 8-machine 24-bus system show that the proposed model can provide a reference for system operators to trade-off the small-signal stability and economy.

In order to reduce carbon emissions, this paper proposes a steel industrial low carbon development model. Firstly, the paper analyses the current situation and bottlenecks in the development of electric arc furnace (EAF) short process steelmaking in China, then the integrated energy system for typical steel industrial community is constructed, and the carbon reduction potential of the steel industry in different contexts by constraining the proportion of EAF steel in the community is explored. The case study shows that the development of EAF short processes can reduce the daily operating costs of the community while reducing carbon emissions, and that increasing the proportion of EAF steel production can contribute to the carbon neutrality goal.

With a large scale of renewable energy connected to the distribution system, the problem of uncertainty will become more obvious due to the huge fluctuation and intermittent characteristics. To ease the effects of uncertainty, static var generator (SVG) is often used to track reactive power fluctuations in the distribution system and compensate. Based on this background, an interval power flow method based on an optimization model is presented in this paper. The tracking characteristic of SVG is involved in this method. The presented method is more efficient and accurate than the existing methods due to its linearized features and considering the tracking characteristic of SVG. Finally, a modified 33-bus distribution system is used to demonstrate the effectiveness of the proposed algorithm.

This paper proposed a method to analyze the transient synchronization stability of the grid-connected doubly-fed induction generator (DFIG) in case of power system failure. Firstly, analyze the voltage source converter (VSC) of the DFIG based on the phase-locked loop (PLL), and establish the grid-connected system model based on the PLL reference frame. Then, the swing equation of the system is deduced, and starting from the existence of equilibrium point, the stable area and the transient motion characteristics of the system, combined with the transient energy function method, the transient energy function of the DFIG that is weakly connected to the grid during the system failure is analyzed. State stability characteristics. Finally, a single-machine infinity simulation model of the grid-connected DFIG was built in MATLAB/SIMULINK. The simulation results verified the correctness of the theoretical analysis and the factors that affect the transient stability of the DFIG.
