Firstly, a bidding strategy based on disappointment avoidance theory is adopted to simulate the self-interested market behavior of prosumers. And then, a sensitivity analysis model based on deep neural network is constructed to embed network constraints which assists the dynamic pricing of network charges for various energy trading. Finally, a P2P transaction mechanism based on two-stage continuous double auction is designed to realize multi-round matching clearing. Numerical cases show that the proposed method reduces the power purchase cost by 5.12% on the premise of meeting the line congestion and voltage constraints, which is helpful to realize the economical and efficient operation of distribution network.","PeriodicalId":165790,"journal":{"name":"2023 International Conference on Future Energy Solutions (FES)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122545812","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 existing evaluation methods such as the Short-Circuit Ratio (SCR) are often based on simplifications which may produce inaccuracies, particularly when studying weak systems. As a result, a misleading estimation of voltage stability can occur, exposing systems to unnecessary renewables curtailment or other inappropriate remedial actions that may cause partial disruptions or potential instability. This paper provides a rigorous analytical revision of voltage stability assessment to confidently evaluate the maximum power transfer under various operating conditions. Subsequently, the proposed approach is applied as an enhanced method of system strength evaluation. The method is extensively tested on a single-machine-infinite-bus test system. Numerical results show a notably more accurate assessment relative to the common alternative methods.","PeriodicalId":165790,"journal":{"name":"2023 International Conference on Future Energy Solutions (FES)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125388683","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}

Despite the availability of innumerable literature on review of reliability in power systems in general or in specific domain area, to the knowledge of authors, not a single work exists in literature till date, which thoroughly reviews the different approaches which have been used to analyze DS reliability.

The studies concluded that the grid’s physics is poorly represented by a constant minRAM specification and that increasing utilization of the grid results. On the other hand, it has not yet been investigated whether a regional- or time-dependent minRAM specification better reflects the grid’s physics and thus can create a better compromise between cost-effective market coupling and increasing congestion management costs.

Empirical trends of the measurement outcome indicate that a linear relation towards the relative U1 level is justified to represent the load current harmonics dependence.

This study aims to provide an in-depth understanding of residential electricity consumption trends in Italy and propose a Long ShortTerm Memory (LSTM) model for long-term load forecasting. Statistical electricity consumption data for Italy were obtained from the International Energy Agency for the period 19902020. The results indicate a fluctuating trend in Italy’s Total Electricity Consumption, with the residential sector experiencing a decline over the last decade. To address this challenge, an LSTM model is proposed for accurate long-term load forecasting of Italy’s total electricity consumption. The model is designed to capture complex temporal patterns, allowing for better planning and management of the country’s electricity infrastructure. This paper highlights the significance of the residential sector in shaping Italy’s electricity consumption patterns and demonstrates the potential of LSTM models in providing reliable and effective load forecasts for decision-makers and stakeholders.","PeriodicalId":165790,"journal":{"name":"2023 International Conference on Future Energy Solutions (FES)","volume":"143 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116048329","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}

Accordingly converter offers a 45% higher gain per component count (at D=0.5) than other reported converters. The current sensor less feature of the proposed converter, which is not common in reported multi-input converters, eliminates the need for inner current loop control during acceleration by supplying 70% of the required peak power (at D=0.6) from the ultracapacitor. The functional capabilities of the proposed converter make it suitable for battery/ultracapacitor-based EV applications.
