Moreover, the designed controller is robust against the shift in resonance frequency of LCL-filter due to filter parameters and line inductance variations.

The transmission lines frequently experience the number of shunt faults that affects the system stability, damages the load and increases the line restoration cost. Therefore, a robust and precise model is needed to detect and classify the faults for the rapid restoration of faulty phases. In this paper, we propose a deep belief networks (DBN) model for FDC based on discrete wavelet transformation which is made of multiple layers with restricted Boltzmann machine (RBM) that enables the model to learn the probability reconstruction over its inputs. The effectiveness of the proposed DBN is tested by using the number of input signals under various sampling frequencies and obtained results compared with existing methods. Results show that the proposed model is capable to perform precise FDC of transmission line.","PeriodicalId":244426,"journal":{"name":"2020 2nd International Conference on Smart Power & Internet Energy Systems (SPIES)","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124087308","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 addition, the UV intensity consisted of maximum, minimum, and average values because it fluctuated during the recording. There were two UV image patterns that could be identified, namely the scattered points and the concentrated light (forming an area).

However, many countries have encountered obstacles in the process of reducing dependency. The obstacles that arise are very specific depending on the conditions of the country. Therefore, the strategies are taken by each country also different. An example is in Indonesia. Indonesia’s National Energy Policy (NEP) has a mandate to achieve N&RE target of 23% in 2025 and 31% in 2050. Because of the unique characteristic of Indonesia, the strategies to achieve these targets differ from other countries. This research used the Java-Bali power system in Indonesia as a case study to find the strategies. A generation expansion planning (GEP) by considering alternative strategies to achieve the target in Java-Bali has been conducted. This research used the MoMANI-OSeMOSYS as a GEP model. Three scenarios have been developed: business as usual (BAU), renewable energy (RE), and new and renewable energy (N&RE) scenario. The results show that the implementation of the N&RE target causes the generation cost increase and the CO2 emission decrease. Achieving the N&RE target requires the role of nuclear energy.","PeriodicalId":244426,"journal":{"name":"2020 2nd International Conference on Smart Power & Internet Energy Systems (SPIES)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116577315","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}
