In this study SEAN, an advanced management system that can be used for coordinating huge number of DERs in VPP applications is proposed. The designed system is aimed to meet supply/demand mismatches, benefiting from various types of storage systems and controllable loads. As a response to an event happening on the grid, both pre-planned and real-time scheduling and coordination tasks are aimed to be handled. During the coordination process, calculations and control actions are tried to be kept as minimal as possible for effective operation.","PeriodicalId":236483,"journal":{"name":"2015 3rd International Istanbul Smart Grid Congress and Fair (ICSG)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114013335","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}

Through the addition of SG technologies traditional electrical grids become more flexible, robust and interactive, and are able to provide real time feedback by employing innovative services and products together with communication, control, intelligent monitoring, and self-healing technologies. For being fully functional, utility operators deploy various SG applications to handle the key requirements including delivery optimization, demand optimization and asset optimization needs. The SG applications can be categorized into two main classes: grid-focused applications and customer-focused applications. Although these applications differ in terms of security, Quality of Service (QoS) and reliability, their common requirement is a communication infrastructure. In this paper, we focus on the use of Next Generation Networks (NGNs) for SG applications. We also present a detailed analysis of a NGN-based communication infrastructure for SG applications in terms of global network statistics and node-level statistics.","PeriodicalId":236483,"journal":{"name":"2015 3rd International Istanbul Smart Grid Congress and Fair (ICSG)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126686002","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}

Therefore, TVPPs facilitate the active participation of DERs in the electricity markets and the optimal operation of them. In this paper, a two stage model for decision making of TVPP is proposed. In the first stage, TVPP minimize its cost with a non-linear programming (NLP). In this stage, DG and DR constraints (i.e. limitations of DG generation and maximum load curtailment) and distribution system constraints (i.e. AC power flows and voltage limits) are considered. In the second stage, the strategic behavior of each supplier is represented via a Supply Function Equilibrium (SFE) model. Therefore, the bidding strategy of TVPP is represented in an intraday electricity market via Nash-SFE. A uniform pricing mechanism is assumed for the market settlement and calculating the supplier profit from selling energy. A typical distribution test system is considered as a TVPP which is connected to the upstream network at a point of common coupling (PCC). Participation of TVPP is investigated in three different load levels of a day. It is demonstrated that the TVPP can get a greater share in electricity market with demand increasing.","PeriodicalId":236483,"journal":{"name":"2015 3rd International Istanbul Smart Grid Congress and Fair (ICSG)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127488022","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}

After the new legislation of market liberalization in Turkey, competition-based on hourly price has received a growing interest in the energy market, which necessitated generators and electric utility companies to add new dimensions to their scope of operation: short-term load and price forecasting. The field has several opportunities though not free from challenges. The dynamic behavior of the market price has caused the electric load to become variable and non-stationary. Furthermore, the number of nodes, in which the load must be predicted, is not constant anymore and can no longer be estimated by experts alone. In this competitive scenario, statistical forecasting methods that can automatically and accurately process thousands of data samples are essential. The purpose of this study is to demonstrate the importance of short-term load forecasting, how it has received a growing interest in Turkey and to propose an artificial neural network that can forecast the short term electricity load. Through detailed performance evaluations, we demonstrate that our forecasting method is capable of predicting the hourly load accurately.","PeriodicalId":236483,"journal":{"name":"2015 3rd International Istanbul Smart Grid Congress and Fair (ICSG)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131769989","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}
