With the rapid development of wind power technology, the capacity of wind power is growing rapidly and monitoring data of SCADA system is also becoming more comprehensive. Faults of wind turbine components are closely related to work condition, so the overall availability of whole wind farm could be improved by focusing on the wind turbines operating in harsh condition. In this paper, a method based on SCADA data to judge harsh condition is proposed. According to historical data of SCADA and fault record, the fault characteristic parameters are selected by Relief algorithm, as the characteristic quantity of failure rate of wind turbine. Taking pitch fault and yaw fault as example, the SCADA data of the actual wind farm are simulated and the effectiveness of the method is verified.

With the promotion of the national carbon neutrality policy, GS's energy consumption structure and industrial structure have changed dramatically. Timely and reliable prediction of the changes of regional industrial structure plays an important role in regional development planning. Industrial electricity consumption characteristics are real-time and objective feedback of production and operation status. Therefore, analyzing the correlation law of industrial electricity can obtain the evolution trend of industrial structure. This paper excavates the socio-economic value of electricity data and establishes a set of analysis framework of regional industrial structure based on industrial electricity correlation topology. Firstly, based on centrality analysis, the regional industry center is obtained from the perspective of power consumption correlation. Secondly, the trends of development in different industries are obtained by curve clustering analysis. Finally, through the topological analysis of industrial electricity, it provides a power perspective to analyze the transformation and upgrading process of regional industrial structure in different periods. The analysis results of the electricity consumption of GS's industries from 2010 to 2020 show that with the promotion and implementation of the national policy and carbon neutrality policy, most industries in GS shows an overall upward trend, and the diversified and Clustered Development Characteristics of the manufacturing industry are obvious. At the same time, on one hand, the national economy is still highly dependent on traditional high energy consuming industries. On the other hand, the elimination of highly polluting industries has achieved remarkable results. The research conclusion can provide energy assistance for the government's precise governance.

In order to ensure the safe and stable operation of multi-terminal flexible DC system and improve the accuracy of single-pole grounding fault location of transmission lines. This paper proposes a single-pole grounding fault location method based on Least Squares Support Vector Machine (LSSVM). When the ground fault occurs, the line mode voltage of different sections in series is combined with the classification mechanism of least squares support vector machine to identify the fault section. Then, the frequency domain characteristics of the line mode voltage in this section are extracted by wavelet packet decomposition combined with Pearson correlation coefficient, and the LSSVM model is established based on the characteristic results to realize fault location. The sparrow search algorithm is used to optimize the parameters of LSSVM model. This paper established ± 500kV four-terminal flexible DC simulation model for testing. The results show that the method has good anti-transition resistance ability, and the location error is within 0.37 km at the sampling frequency of 50 kHz.

Security and stability control system is the second-defense-line to maintain the safe and stable operation of power system. Aiming at the problem of control strategy failure and mismatch in security and stability control system under strong uncertainty, a new emergency control decision system architecture is proposed to adapt to the strong uncertainty of power system. The system adopts a parallel interactive architecture composed of data processing and interaction subsystem, safety and stability simulation calculation subsystem and emergency control strategy optimization subsystem, dynamically adjusts the margin control target value so that the system can adapt to the rapid changes of power grid mode and control measures, and quickly evaluates the adaptability risk of emergency control on duty strategy to deal with AC and DC cascading faults. Based on the convex and concave coefficients of the safety and stability margin control target value, the emergency control strategy is sliced and verified by simulation, so as to realize the rapid optimization of the emergency control strategy coupled with multiple types of safety and stability problems. The application case of the actual power grid verifies the effectiveness of the system, and can adapt to the uncertain changes of the power grid operation mode and control measures.

Smart microgrids (SM) can be seen as unified agents after traditional microgrids empower autonomy. Different from the static risk assessment of traditional microgrids, the autonomy of SM makes it difficult to evaluate with classic static risk assessment indicators such as load loss risk, voltage or power flow overrun risk. What's more, it is prone to false data injection attacks and makes its normal operation invalid since SM has lots of IoT facilities. Therefore, it is necessary to conduct static risk assessment on SM considering false data injection attacks. In this paper, voltage overrun risk, power flow overrun risk and comprehensive risk are taken as indicators of static risk assessment, and a set of static risk assessment process is designed against the background of clearing SM internally by false transaction data injection attacks. Further, a 7-node SM with multiple renewable energy is taken as an example to verify the effectiveness of the proposed static risk assessment method.

The planning and design of multi-energy complementary energy system is the primary key technology to ensure its safe, economic and reliable operation. Since the multi-energy complementary micro-grid contains various energy sources such as heat source and power source, and various types of energy-using loads such as heat load and electric load, the source, network and load have strong coupling relationship, and the renewable energy sources such as solar and wind have strong volatility, and the system operation scenarios are complex and diverse, it is difficult to apply the conventional planning methods directly. Therefore, in this paper, we propose a multi-energy complementary micro-grid planning method that considers the coordinated interaction of source, load and storage in detail, fully accounts for the uncertainties on the source and load sides and the coordinated coordination of multiple energy flows, establishes a user-side demand response model, which fully considers the operational constraints of interruptible load, transferable load and user satisfaction; proposes a dual-layer planning method, and proposes a black-box time-consuming solution method for the solution of the dual-layer optimization model, which effectively ensures the rapid solution to obtain the planning capacity of renewable energy sources, cogeneration units, thermal and electrical energy storage systems and other devices.

Aiming at the problem of optimal planning of large-scale distributed renewable energy resources and loads, a distributed renewable energy bi-level planning method based on cluster division was proposed to maximize the overall benefits of distributed renewable energy clusters. The upper layer takes the energy exchange between clusters and the optimal stability and reliability of the system as the guiding principle, and establishes a comprehensive performance index with cluster resemblance and active power balance as the core to obtain the optimal cluster division result. The lower layer takes economy and reliability as the goal. Each cluster is regarded as a new planning unit, and the integrated planning method is used for capacity allocation and grid design, and the optimization results are fed back to the upper cluster division. Cross iteration between two layers forms a closed-loop planning and design method for distributed renewable energy cluster planning. The example shows that the proposed method effectively reduces the energy storage capacity configuration of distributed renewable energy cluster and improves its economy and reliability.
