So power system flexibility plays the main role in secure and reliable power system operation. Variable generation specially wind and solar are two main sources of flexibility decrement challenge in power system On the other hand energy storage equipment helps to overcome this challenge by insertion or absorption electrical energy by sufficient capacity and ramp rate. Flexibility metrics is a good tool for power system flexibility evaluation and can help to comprise the level of flexibility of power system in different situations especially in operational planning and real time operation. In this paper a new flexibility metric is developed for power system incorporated wind farm in the presence of energy storage equipment for power system flexibility evaluation. This metric includes two main parts of energy capacity and ramp rate of energy storage each of them improves the power system flexibility. The comparison of this metric with and without the energy storage can quantify the role of this equipment and also can be used for economic analysis by the concept of flexibility value.","PeriodicalId":359817,"journal":{"name":"2019 International Power System Conference (PSC)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131887474","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}

Modern distribution networks, in addition to the importance of economic issues, must operate at an acceptable level of system reliability, Failure to pay attention to the reliability importance can lead to irreparable damages in the distribution network. Toward this end, energy not supplied as a reliability index along with operation cost are considered as objective functions. Also, the effect of uncertainty resources related to solar photovoltaic arrays power generation and electricity price are considered in the optimization problem evaluations. Considering the effects of distributed generators and energy storage units causes the proposed problem more be complicated. For this reason, an improved particle swarm optimization algorithm is provided to deal the complexity of the problem. The proposed algorithm is tested in the IEEE 33-node test system, and its superiorities are shown through comparison with other evolutionary algorithms.","PeriodicalId":359817,"journal":{"name":"2019 International Power System Conference (PSC)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123842521","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 most important feature of these insulators is their hydrophobicity. Contamination and aging are some of the factors that weaken this important feature and reduce the reliability of these insulators. Due to aging effects partial discharges start on the surface of the composite insulators and increase by impact of external factors. This paper examines the occurrence of partial discharge signals on polymeric insulators under: varying amounts of contamination, impact of physical defects, and accelerated salt-fog aging process. The partial discharge signals of these insulators are detected by UHF antenna and they are recorded. These measured partial discharge signals are used to monitor the insulation status. Their characteristics are determined through feature extraction. Using these “extracted features”, a good distinction is found among these captured signals; which relate to different samples characteristics in terms of: severity of pollution, or different mechanical defects. These features are selected and used for classifying the insulators condition by support vector machine (SVM) algorithm.","PeriodicalId":359817,"journal":{"name":"2019 International Power System Conference (PSC)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122577392","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}

One of the most popular solutions is to use small transformers to reduce the length of the low voltage feeders in order to decline losses in these parts of the distribution networks. By analogy, in this paper, a new techno-economic method is proposed in order to contend with the aforementioned problems. The effectiveness of the method is evaluated by using several test systems. Self-adaptive PSO is selected as a metaheuristic optimization algorithm due to its high exploration and exploitation nature and fast convergence. Equivalent uniform annual cost is selected as a simple but effective tool so as to split the cost of the initial investment. The objective function is defined to minimize not only the initial investment but also the operation cost, simultaneously.","PeriodicalId":359817,"journal":{"name":"2019 International Power System Conference (PSC)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117282307","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}
