An adjustable potential assessment and interaction framework of air conditioning thermostatically controlled load cluster participating in distributed photovoltaic consumption based on data-driven and Deep Belief Nets (DBN) is proposed in the power market environment. Firstly, a data-driven adjustable potential assessment model based on Deep Belief Nets is constructed to output the adjustable potential of thermostatically controlled load cluster in real time. Secondly, within the certain range of power adjustment, a demand interaction framework based on Deep Belief Nets is also constructed to regulate the real-time temperature setting of thermostatically controlled load cluster. Finally, taking a 10KV feeder in Northern Hebei as an example, the results show that the proposed framework can make full use of the adjustable potential of the thermostatically controlled air-conditioning load cluster, quickly and accurately participate in the consumption of distributed photovoltaic, and have high engineering application value.","PeriodicalId":447871,"journal":{"name":"2022 5th International Conference on Power and Energy Applications (ICPEA)","volume":"400 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116679886","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}

This paper proposes a new approach for virtual inertia emulation which eliminates the counteractive action of inertia. A frequency response model is also proposed which reduces the energy storage (ES) rating when inertia response (IR) and primary frequency response (PFR) are deployed. The region reduction iterative algorithm (RRIA) is used to size the ES power and energy ratings for PFR. The ES rating for IR is derived analytically. A case study of an Offshore Oil and Gas Platform (OOGP) in the North Sea, which is a typical low-inertia system, is presented. The results show that the new approach for inertia emulation reduces the ES rating when IR is deployed alone. Also, the results showed that the frequency response model is able to reduce the ES rating when using IR and PFR.","PeriodicalId":447871,"journal":{"name":"2022 5th International Conference on Power and Energy Applications (ICPEA)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126833994","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}

There is still a lack of quantitative evaluation of the technical advantages of flexible interconnection in distribution networks. In this paper, the application scenario of the flexible interconnection of the medium voltage distribution network is defined mathematically. On this basis, the technical performance improvement brought by the flexible interconnection is quantitatively analyzed. Case analysis results show that: compared with the original AC system and the AC interconnection scheme, the DC flexible interconnection scheme can significantly improve the overall power supply capacity, the distribution system utilization rate, the power supply reliability, and the distributed new energy acceptance capacity, meanwhile the energy efficiency of the whole distribution system is equivalent to the original AC system. So as a conclusion, this paper provides support that the flexible interconnection based on MVDC has good application value in urban distribution network with tight distribution channels, unbalanced load distribution, and high requirements for power supply reliability.","PeriodicalId":447871,"journal":{"name":"2022 5th International Conference on Power and Energy Applications (ICPEA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126384302","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}

That is, the unbalanced power caused by the fault of the receiver on the AC side of the flexible DC transmission is consumed. The energy dissipation resistance on the DC side of the flexible DC transmission system is used to transplant the unbalanced power of the receiver grid, which can prevent the overcurrent accident caused by the fault of the communication system and achieve the purpose of power balance in the flexible DC transmission system.
