Under the background of renewable energy penetration increasing and energy conservation becoming social concerns, the joint operation of power distribution system and water distribution system could reduce the overall operation cost, improve social welfare and improve the flexibility of system operation. In this paper, we model the power distribution system and water distribution system, and simplify this model based on piecewise linear method. Then we obtain the model of power-water distribution system, which is a mixed integer linear programming problem. While the joint system is complex and the time spent on solving problem is too long for engineering application. Thus, in this paper, we propose an adaptive time clustering method based on the characteristic of the net load curve of power and water. We use an iterative algorithm to decide whether two adjacent time clusters could be merged into one in the joint operation problem. The case studies that the joint day-ahead operation problem, which proves that the model and method proposed in this paper could reduce the solution time while maintain high precision. It could meet the requirement of engineering application.","PeriodicalId":127882,"journal":{"name":"2021 6th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128283717","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}

We combine Faster RCNN model with Wasserstein GAN model, and propose Enhance RCNN model especially for the low resolution object detection in the substation. In our model, discriminator in GAN is used to distinguish the abstract feature difference between the high resolution object and the low resolution object after supplementing feature. And generator is used to supplement the abstract feature for low resolution object, so that its feature distribution is consistent with the feature distribution of high resolution object, thus improving the overall detection effect. The experimental results show that for the typical object in the substation such as person, bicycle and vehicle, Enhance RCNN model averagely improves mAP (Mean Average Precision) and IoU (Intersection-over-Union) by 7.79% and 6.57% respectively when is compared with the other models including Faster RCNN, Fast RCNN and SSD. For the low resolution object whose ratio of the object pixel to total image pixel less than 0.2%, Enhance RCNN model averagely improves mAP by 10.44%.","PeriodicalId":127882,"journal":{"name":"2021 6th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129251657","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}

These advancements have been mainly attributed to the ubiquitous data communication in the grid. However, low sampling frequency will limit the utilization degree of data because low frequency measurement power data contains little information. The existing methods of reconstructing the low-frequency sampling data into the high-frequency sampling data have poor accuracy of data reconstruction since most of them failed to capture the characteristics of power data. This paper proposes a novel method based on super-resolution generative adversarial network (SRGAN) to address this issue. First, we convert power data into data-images. Furthermore, the data-images are used to train the SRGAN model. Finally, the trained generator can be used to reconstruct the low-frequency sampling data into the high-frequency sampling data. Numerical experiments have been carried out based on photovoltaic (PV) power generation time-series data from the State Grid Corporation of China with separately reconstruction of the irradiance and PV power datas. The results demonstrate the superior performance of the proposed method compared with a series of state-of-the-art methods.","PeriodicalId":127882,"journal":{"name":"2021 6th Asia Conference on Power and Electrical Engineering (ACPEE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116308168","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}
