Vigorously developing new energy sources such as wind power is an important means to achieve the dual-carbon goal. But, wind power output is fluctuating and random, and its prediction accuracy improves with the shortening of the time scale, and the regulation rate of conventional thermal power plants is slow, making it difficult to cope with real-time wind power and load. Therefore, the traditional day-ahead scheduling strategy has been difficult to meet the requirements of system flexibility and economy. Based on this problem, this paper proposes a multi-time-scale low-carbon economic dispatch strategy for power system considering the time-shift characteristics of CCPP energy consumption. Firstly, the energy consumption time-shift characteristics of the integrated flexible CCPP are analyzed, and its participation in multi-time scale low-carbon scheduling mechanism and scheduling advantages are discussed, and a multi-time scale framework is given. Secondly, aiming at the optimal total system cost, constructs a day-ahead intra-day real-time three-stage low-carbon economic dispatch model of the power system. Finally, the dispatching model is solved by using the commercial optimization software CPLEX. The results of the IEEE-39 node calculation example show that the dispatching strategy proposed in this paper can effectively reduce the phenomenon of wind curtailment and load loss, and achieve the goal of low-carbon economic dispatch.

Photovoltaic power generation is an important part of the development of green energy, and the dust deposited on the surface of photovoltaic panels can affect the power generation efficiency of photovoltaic power plants through a variety of ways. Therefore, the production needs to detect the surface cleanliness of photovoltaic panels to determine whether the cleaning work of photovoltaic panels is needed. There have been many methods to detect the cleanliness of the photovoltaic panel surface or the dust coverage on the photovoltaic panel surface. In this paper, we propose a ratio of power to illumination method to detect the cleanliness of photovoltaic panel surface from the power perspective with the help of the linear relationship between illumination and photovoltaic panel power generation. The ratio of power to illumination method needs to measure the power and illuminance at each time point under a fixed time difference, and use the ratio of power to illuminance to determine the size of the effect of dust on the photovoltaic panel and initially detect the cleanliness of the photovoltaic panel surface. The ratio of power to illumination method also introduces the ratio of unit illuminance power to specifically indicate the size of the impact of dust on photovoltaic panels, standardize the detection of photovoltaic panel surface cleanliness, and help for production practice with the help of the threshold value of the ratio.

Modern digital power applications (e.g., power trading system) are moving toward microservice architecture, in which each service is developed and managed independently, and new features and updates are delivered continuously. It is essential to manifest the performance problem of the application early and often, before the code ships to the production. In this paper, we propose a novel performance testing and analysis approach for microservice based application, which first designs a multi-objective search technique to expose the performance problem, and then detects potential performance bottleneck by aggregating and comparing normal/abnormal traces. The evaluation results on an open source microservice benchmark and an industrial digital power application show that our approach is effective, and can expose performance anomaly and detect performance bottleneck effectively.

Application of small rotorcraft unmanned aerial vehicle (UAV) is expanded greatly with the improvement of its performance, which will lead to the increase of power units. To satisfy the different voltage requirements of these power units, a single-input and multiple-output converter is required during the development of small rotorcraft UAV. Here, we developed a single-input dual-output converter that can output two different voltages. The topology and working principle of the converter were analyzed. We then designed the basic structure of the converter. Furthermore, operation of the single-input dual-output converter was simulated using Simulink in Matlab. The voltage output of the converter was detected by oscilloscope. Our results indicate that this converter can satisfy the requirement of different voltage outputs of small UAVs.

The sheath circulating current of some high-voltage cable exceeds standard, and the circulation suppressor can alleviate this problem to some extent. However, if ground fault happens, the short-circuit current will flow through the circulation suppressor, resulting in over voltage. Therefore, a circulation suppression method for short-circuit current guidance was proposed. The influence of impedance angle, installation phase and impedance ratio of suppressor on the suppression method were analyzed, and the results showed that the circulation suppression method of short-circuit current guidance had the characteristics of circulation suppression, fault current guidance and high safety.

As wind power is integrated into the power system, it poses challenges to frequency stability. Wind power needs to participate in frequency regulation, and reserving power is found to be an effective method. However, the amount of excessive or insufficient power deloading affect the economics and requirements of PFR. On the other hand, different power deloading allocation among wind turbines of wind farm affect dynamic performance of PFR. This paper proposes an optimal allocation method for wind turbine reserves within the farm with the object of minimizing kinetic energy loss of wind turbines to improve performance of the farm during PFR. Furthermore, the pitch angle of each wind turbine is calculated through the analytical relationship between the power deloading. The simulation results demonstrate that this method can significantly improve the primary frequency regulation performance of the wind farm in the power system.

The harmonic distortion level of nonlinear load in distribution network has been widely concerned. At the same time, the monitoring of distribution system is insufficient, and it is difficult to reflect the overall harmonic level by setting fewer harmonic monitoring points. In order to solve this problem, this paper proposes a method to determine harmonic monitoring points by using voltage value according to the correlation between voltage value and harmonic distortion rate. The proposed method for setting harmonic monitoring points uses the fundamental voltage value of each bus collected from traditional smart meters. By comparing the correlation between fundamental voltage index and harmonic voltage distortion rate, it is found that the fundamental voltage index has a strong correlation with harmonic voltage distortion rate. It is proposed to use Pearson correlation coefficient matrix of fundamental voltage index to determine harmonic monitoring nodes through optimization algorithm. In this paper, IEEE-14 node is used to verify this method. The results show that the harmonic level of the whole distribution network can be reflected by setting a few harmonic monitoring points.

At present, photovoltaic power generation has been widely used and more photovoltaic power stations are constantly connected to the power system, which put forward higher comprehensive requirements for the planning and operation of power system on the macro scale. From the point of view of data feature mining and correlation, this paper proposes a method for generating typical scene sets of photovoltaic load correlation taking into account meteorological factors. Firstly, HDBSCAN clustering is used to cluster the comprehensive operation data of the system in the planning period and to screen out typical scenarios. Then different typical scenarios are fused by FP-growth correlation using meteorological characteristics. Finally, a typical set of associated scenarios including the operation of photovoltaic power system is obtained. Taking a city power grid as an example, the correlation typical scene method and the traditional whole-year time sequence method are compared and analyzed. The scenario set of this method contains a series of load and photovoltaic indicators to provide a more comprehensive macro description of the scenario. The experimental results show that the scene set generated by this method can improve the computational efficiency while maintaining a good accuracy. This provides more references for planners on medium and long-term time scale for PV-based power system data, improves the comprehensiveness and scientificalness of planning, and meets the needs of power system for medium and long-term data scenarios.

The integration of renewable energy sources (RES) such as wind power and photovoltaic have helped to alleviate the problems of energy shortage and environmental pollution. However, it has also presented new challenges to the frequency regulation of the power grid, raising higher requirements on the frequency regulation capability of existing thermal power plants (TPPs). To ensure that TPPs can better accomplish their mission of frequency regulation, this paper proposes a cooperative control method for integrated thermal power plants-energy storage system (TPP-ESS) based on combustion rate feedback. This method significantly improves the effect of TPPs when they participate in secondary frequency regulation by utilizing the rapid response capability of ESS. Furthermore, an active recovery strategy for the state of charge (SOC) is proposed to recover SOC of ESS when needed by using TPPs. Finally, simulations in MATLAB/Simulink are conducted to validate the proposed strategy's effectiveness.
