In this paper, the mechanical characteristics, charging/discharging control strategies of switched reluctance motor driven large-inertia flywheel energy storage system are analyzed and studied. The switched reluctance motor (SRM) can realize the convenient switching of motor/generator mode through the change of conduction area. And the disadvantage of large torque ripple is weakened in the large inertia load application. It has a certain potential for application in flywheel energy storage systems. For motor mode, the optimal switching angle is established by means of off-line simulation. The maximum output torque is guaranteed and the charging time is shortened by this method. During the discharge process, an online optimal control strategy is used to achieve the optimization of generation efficiency, and the maintenance of the command bus voltage is guaranteed by DC-bus voltage monitoring. The above control strategy is verified by simulation.

In view of the problem that the door of the low-voltage power distribution box is opened for no reason under the premise that the intelligent terminal has been installed in Power Internet of Things, an intelligent and safe low-voltage integrated power distribution box is improved and designed, the distribution box is equipped with a face recognition function. If the door of the low-voltage power distribution box is opened, the data signals related to the door opening will be transmitted to the main station by the intelligent terminal and fed back to the personnel on duty in time, which is convenient for relevant personnel to deal with it in time. The experimental results show that the safe opening success rate of the intelligent low-voltage integrated distribution box is not less than 99%, which can prove that it is reliable and can be used in the operation of the actual distribution system.

The overlap and coverage of objects can affect the grasping success rate for robot manipulator grasping in multi-object scenarios. We propose an enhanced grasping algorithm based on YOLOX-that can predict the bounding box with a smaller aspect ratio, thereby more accurate spatial location. Due to the limits of sensor's environment and physical factors, the depth map will lose some depth values. We propose a depth value repair algorithm based on the FMM algorithm, through which the lost depth values in the grasping region can be repaired. In pose estimation, we use the aspect ratio of the bounding box to determine the rotation angle of the robot manipulator jaws. We use a six-axis robot manipulator combined with a depth camera to achieve object grasping in multi-object scenes. The experimental results show that the enhanced grasping algorithm makes the grasping area prediction more accurate, and the distance between the object and the camera is obtained more accurately.
在多目标场景下,物体的重叠和覆盖会影响机械手抓取的成功率。我们提出了一种基于yolox的增强抓取算法,该算法可以以更小的纵横比预测边界框,从而更准确地进行空间定位。由于传感器环境和物理因素的限制,深度图会丢失一些深度值。提出了一种基于FMM算法的深度值修复算法,通过该算法可以修复抓取区域中丢失的深度值。在姿态估计中,我们使用边界框的纵横比来确定机器人机械手下颚的旋转角度。采用六轴机器人机械手结合深度相机实现多目标场景下的物体抓取。实验结果表明,增强的抓取算法使得抓取区域的预测更加准确,物体与相机之间的距离获得更加准确。

Owing to uncertain renewable energy output, how to reduce wind and light curtailment has become one of the problems of power grid peak shaving. This paper proposes an optimal dispatching model for the integrated energy system with hydrogen energy, which considers the integrated demand response of power and heat, under the premise of meeting the primary energy demand of the user side.

Under the background of “double carbon”, in order to effectively improve the energy utilization of regional integrated energy system (RIES), reduce carbon emissions, and improve the flexibility of system operation, this paper proposes a multi-objective optimization model based on PARETO-GWO and considering demand response RIES. Firstly, the modeling is carried out for RIES containing cooling, heating and electricity. Then a demand response model containing transferable, curtailable and replaceable thermal and electric loads is established. Finally, by intro-ducing external population Archive library and Pareto-based non-dominated solution GWO algorithm to obtain mul-ti-scenario operation strategies, the impact of demand response on RIES multi-objective optimization and power bias of units with different operation strategies are analyzed and demonstrated, and it is verified that multi-objective opti-mization can achieve more effective unification of system operation cost and carbon emission than single-objective scheduling.

In order to solve the harmonic problem generated by the electrolytic cell in the high proportion of power electronic equipment and photovoltaic hydrogen generation microgrid, we propose an improved instantaneous reactive power detection method. A harmonic voltage compensator is designed to suppress the voltage harmonic in the photovoltaic hydrogen generation microgrid by dividing the frequency based on the traditional virtual synchronous generator control strategy. This method provides inertia for the distributed power supply of the photovoltaic hydrogen generation microgrid, effectively suppresses the internal harmonic problem of the photovoltaic hydrogen generation microgrid, improves the power quality of the microgrid, and reduces the hydrogen production energy consumption of the electrolytic cell. The simulation results show that this method can realize fast frequency division detection and improve the accuracy of voltage harmonic compensation.

Blast furnace smelting has high energy consumption and large carbon dioxide emissions, which is an important device for energy saving and carbon reduction transformation in the iron and steel industry. In this paper, a multi-objective optimization model of the blast furnace dosing and operation is proposed. This model is to minimize energy consumption, CO2emissions per tonne of iron and generation cost by adjusting the dosage of different inputs. The Pareto optimal solution set of the model is solved by using the NSGA-II algorithm. To verify the effectiveness of the proposed multi-objective model, the optimized dosing and operation is compared with raw operation data, and the comparison results indicate that the proposed model can significantly improve energy conversion efficiency, reduced the carbon emissions, and save operation costs.

With the increasing scale and complexity of power system operation, in order to further improve the efficiency and accuracy of electromagnetic transient modeling of large-scale power systems, this paper proposes a set of fast conversion modeling methods from electromechanical transient simulation software BPA to electromagnetic transient simulation software RTDS for electrical models. The key technologies of fast modeling from BPA electromechanical transient model to RTDS electromagnetic transient model are introduced in detail from data parsing and verification, data pre-processing, sub-system division, model conversion and automatic layout wiring, and the system is applied to the study of RTDS automation modeling in a province of Southern Power Grid.

Implementing energy conservation strategies is an important means to help achieve the dual carbon goal. Conducting energy conservation potential assessments and the achievability of emission reduction targets in the light of the characteristics of the new phase is important for setting reasonable energy conservation and emission reduction targets and safeguards. Based on the 2015–2020 energy consumption and other statistical data of Fujian Province, this paper uses the Long-range Energy Alternatives Planning System (LEAP) model as a research tool to simulate the future end-use energy consumption demand and CO2 emission trends in Fujian Province under different development scenarios by setting up a base scenario and an energy saving scenario, and to analyse the direction and path of low-carbon urban development. The results show that under the baseline scenario, energy demand and carbon emissions in Fujian Province will continue to grow; under the condition of strengthening energy saving and emission reduction measures in Fujian Province, energy demand and carbon emissions in Fujian Province can grow slowly or even decline in the future.
实施节能战略是实现双碳目标的重要手段。根据新阶段的特点,开展节能潜力评估和减排目标可达性评估,对制定合理的节能减排目标和保障措施具有重要意义。本文以福建省2015-2020年能源消费等统计数据为基础,以LEAP (remote energy Alternatives Planning System)模型为研究工具,通过设置基础情景和节能情景,模拟福建省未来不同发展情景下的终端用户能源消费需求和二氧化碳排放趋势,分析低碳城市发展的方向和路径。结果表明:在基线情景下,福建省能源需求和碳排放将持续增长;在福建省加强节能减排措施的条件下,未来福建省的能源需求和碳排放量可以缓慢增长甚至下降。
