As a more complex simulation method, digital twins are more extensive in time scale compared with the traditional power system simulation, and more frequent in data interaction with the real system. Digital twins can be applied in power systems in a variety of ways. But at present, the application of digital twin still stays on the application of the whole product life cycle. This paper proposes a new real-time interactive power system simulation architecture based on the digital twin, and set up an electric power system based on SoC platform of digital twin, PL part has set up a twin body for the electric power system, the PS part compare the difference between the twin body and the actual body and then modify the twin body. It also provides the control part which is consistent with the hardware control logic. The platform is lightweight, economical, heterogeneous and compatible with a variety of computing tasks, rich interfaces and strong expansibility. This paper provides a framework for the application of digital twins in power system and provides the platform with rich application value.","PeriodicalId":223198,"journal":{"name":"2020 5th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115753741","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 offshore wind farm, due to the bad working environment including the high wind speed, high corrosive environment and complex conditions of wind, wave, tide and surge caused by extreme weather such as typhoon, the wind turbines with higher performance and higher power are required. Thus, this presents greater challenge for the selection of offshore wind turbine. An analytic hierarchy process (AHP) is developed to choose the wind turbine suitable for offshore wind power plant. The important factors influencing the selection of offshore wind turbine are put forward with advice from experts and the existing experience. Furthermore, based on the AHP, a three-layer evaluation model and judgment matrix is built. After the weight of each factor is calculated, and the consistency of judgment matrix is verified, the best target model with the best comprehensive evaluation would be select. For an actual offshore wind farm project, the wind turbine with the largest weight is the final option by sorting the comprehensive weight of alternatives. The results show the model is feasible and could be applied to the selection of offshore wind turbines for the future offshore wind power of large-scale development.","PeriodicalId":223198,"journal":{"name":"2020 5th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114636910","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 some regulation markets, the frequency regulation performance is a key index/score and it affects the revenue of the service’s provider. Some studies have focused on modeling the regulation performance score by simplifying or linearizing the performance’s statistical function. However, since regulation signals are usually broadcasted every 2 seconds, there are at least 1800 variables denoting the response power in the existing models. This will make the optimal bidding in regulation market computationally expensive and difficult to solve. Moreover, the regulation revenue function is a kind of nonlinear function. It is difficult to derive optimal solution in a nonlinear optimization. To solve those problems, in this paper, we propose the models of frequency regulation performance for thermal units (TUs) and virtual power plants (VPPs) by linear regression. With the proposed models, we prove the regulation revenue functions are linear. Meanwhile, simulation illustrates that the proposed models need less variable and the models are more computationally efficient than existing methodology.","PeriodicalId":223198,"journal":{"name":"2020 5th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115066715","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 solve this problem, this paper establishes the model of coal-to-electricity project from two aspects of spatial layout and construction time sequence. In the solution of the model, the weighted Voronoi diagram method is firstly used to partition the area to form multiple partition schemes. Then, using the idea of dynamic programming, the problem is divided into several stages. In a single stage, the genetic algorithm is used to obtain the optimal substation planning scheme of the corresponding partition scheme, and the backtracking algorithm is used to generate the timing sequence decisions. Finally, the optimal planning scheme is obtained by calculating the sum of annual investment in each stage through reverse recursive method. The results show that the scheme can meet the requirements of distribution network in practical construction.","PeriodicalId":223198,"journal":{"name":"2020 5th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117159684","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}
