Firstly, the digital power grid model is constructed based on the digital twin technology, and the operation mode of the digital twin power grid is introduced in detail. Then, the time convolution network (TCN) and the gated recurrent unit (GRU) network are fused to design the GRU-TCN prediction model. The high-dimensional data features extracted by TCN are input into the GRU network for learning to enhance the model prediction performance. Finally, the GRU-TCN model is applied to the load forecasting of digital twin power grid, and the high-precision forecasting results are obtained. The experimental results based on the simulation platform show that the proposed method prediction results root mean square error is 28.428KW, and mean absolute percentage error values is 2.161%, which prediction effect is good.","PeriodicalId":198086,"journal":{"name":"2022 Asian Conference on Frontiers of Power and Energy (ACFPE)","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124057257","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 this paper, the controller transforms the mobile device management and access point assignment problem into a joint optimization problem and solves it using adaptive time windows as a tool. Finally, a deep reinforcement learning traffic scheduling algorithm is used to optimize the capacity of the access point and reduce the delay of data transmission.

To ensure the stability of the market operation during the transition stage of the low-carbon power system, supervision methods for market adjustment models and adjustment mechanisms are of vital importance. To handle the uncertainties and fluctuations of renew ables, the construction of ancillary service markets has drawn special attention. However, the supervision methods for ancillary service markets in China are lacking. As one of the earliest countries in the world to carry out the reform of the electricity market, the supervision system of the US electricity market is relatively mature, which can provide enlightenment to the establishment of China's supervision system. With this in mind, the current supervision system of the US electricity market is reviewed from the perspectives of power regulators and supervision content and measures in this paper. The evolution of the regulatory structure of the US electricity market is reviewed and supervision measures of various types of ancillary services markets are introduced and analyzed.

Based on the analysis of the characteristics of large scale failures of the distribution network in extreme weather, a fault recovery strategy considering repair sequence is proposed to improve the power supply capacity of the distribution network. A two-layer distribution network reconfiguration model considering both reliability and costs is established. Considering both the reliability and the economy, the loss load and the cost of distributed generation are minimized at the upper layer and the lower layer, respectively. Firstly, the statues of tie switches are adjusted after the network failure to construct the new radial network and obtain the topology based on the graph theory. Then the dynamic programming method is utilized to determine the optimal topology and the fault repair sequence. Taking the improved PG&E 69 node system as an example, the effectiveness and practicability of the proposed method for fault recovery under extreme disasters are verified.","PeriodicalId":198086,"journal":{"name":"2022 Asian Conference on Frontiers of Power and Energy (ACFPE)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134438077","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}

The currently single-ended protections, configured as primary protection in HVDC projects, have inadequate sensitivity with high resistance faults. To overcome these shortcomings, a novel protection scheme using single-ended line current from already existing measurement unit in HVDC projects is proposed in this paper. With current fluctuation extracted, floating threshold current criterion is proposed to distinguish internal and remote external faults. Based on variable current, fault direction and faulty line can be reliably identified. RTDS simulation results verify that the proposed protection scheme can act sensitively and quickly. The action time is not more than 1.2ms and 3.2ms when faults with $0Omega$ and $800 Omega$ resistance respectively occur in the range of the whole line. Compared with other single-ended protections, the proposed method has advantages of detecting the high resistance fault, small operation time.","PeriodicalId":198086,"journal":{"name":"2022 Asian Conference on Frontiers of Power and Energy (ACFPE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131132103","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}
