Because there are complex time and space coupling relationships among flexible resources, the traditional active-reactive power dispatching strategy is no longer applicable. In order to effectively consume renewable power, this paper proposes a day ahead economic dispatching method considering flexible resources. Its characteristic is that on the basis of relaxation power flow, the reactive power support and power loss of energy storage (ES) are effectively considered through the constraint of cone form. Through the case study of the improved IEEE 33 node, it is found that the coordination of active and reactive power can be taken into account when the power grid operation conditions are established in the form of cone constraints. The operating voltage of the power grid keep in a perfect range.","PeriodicalId":402897,"journal":{"name":"2022 IEEE International Conference on Power Systems and Electrical Technology (PSET)","volume":"217 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133677960","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to effectively restore the power routing of the distribution network, the operators need a faster and more efficient optimization method to dynamically design the topology. Therefore, a new distributed algorithm-based distribution network reconfiguration method is proposed in this paper. In the proposed method, two main costs are comprehensively considered, switching cost and operation cost, a reconfiguration optimization model of the distribution network is established and solved by the distributed Bias Min-consensus algorithm, which can find the solution with a fast speed in dynamically switching topology. Moreover, a probability based method is adopted to generate the failure scenarios of the distribution network in the extreme events.

Distinguished from traditional local control, centralized control and model-based distributed control, this paper proposes a data-driven/model-based multi-agent deep reinforcement learning (MADRL) -based voltage control method while minimizing active and reactive power adjustment costs. Without the knowledge of the network topology and fully state information, the proposed method can quickly regulate the bus voltages within proper thresholds.

The current residential tiered electricity price mechanism plays a rather limited role in energy saving. In order to study the actual situation of residential electricity consumption, ensure the fair participation of industrial and commercial users in the electricity market, promote energy conservation and emission reduction, and maximize social welfare, many related studies have been produced. On the basis of predecessors, this paper combs the domestic and foreign residential electricity price pricing theory, analyzes the current domestic residential electricity price, and establishes the residential step electricity price optimization model.

However, the fluctuating medium DC voltage caused by the 24-pulse diode rectifier brings the potential input voltage sharing problem. To address the unbalanced input voltage issue, this paper adopts the triple-closed loop decoupling control strategy to mitigate the influence of the output voltage loop on the input voltage sharing loop. The smallsignal analysis and the impedance modeling of the ISOP-DAB are derived and verified by the frequency scanning test. The input voltage sharing effect is guaranteed in the simulation test under mismatched electrical parameters and unbalanced input voltage. Furthermore, the stability of the cascaded power supply system is analyzed.","PeriodicalId":402897,"journal":{"name":"2022 IEEE International Conference on Power Systems and Electrical Technology (PSET)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127115910","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An efficient insulation defects recognition method based on autonomous feature extraction of convolutional neural network (CNN) is proposed in this paper. Original partial discharge signals of four defects are obtained through experiments firstly, then the time-domain waveform image is taken by the skills of graying and clipping as the input of CNN for classification. The influences of different convolution layers, pooling methods, activation functions, convolution kernel sizes and input image sizes on the network performance are studied comprehensively. Experiments demonstrate that our method could achieve the overall recognition rate of 96%, which is 3.2% and 6.0% higher than that of SVM and BP neural network, respectively.
