Reserve provision for the balancing of the network is an important service that, in principle, should be provided by all the units connected to the network, including RES generators themselves as well as flexible loads and storage systems. However, these resources have big peculiarities tied with their relevant technologies and could, beyond providing local services within the distribution grids (e.g. voltage regulation, congestion management), be available to provide reserve for the entire system, through the connection points to the transmission grid. This paper shows a more advanced dispatching management of distribution systems by resorting to more advanced Information and Communications Technology(ICT) systems able to transform distribution from a “passive” into an “active” system and market architectures able to incorporate scattered bids coming from distributed generation and active load. A delicate point is the interface between transmission and distribution that has to be managed in a coordinated manner between Transmission System Operators (TSO) and Distribution System Operators (DSOs) in order to achieve an overall efficiency target. ICT should also be key to allow a strict real-time coordination of the different subjects that are in charge to actuate the provision of ancillary services. Further, the paper shows as new actors could appear in the system like the “aggregators” who interface with the Market Operator to submit the bids for the provision of the services, with the local TSO to receive the consequent dispatching orders, with to the aggregated distributed resources (generation, flexible demand, storage) and with to the involved DSOs, in order to communicate how each dispatching order will in turn be dispatched among the distributed resources it aggregates.","PeriodicalId":134414,"journal":{"name":"2015 International Conference on Smart Grid and Clean Energy Technologies (ICSGCE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124066749","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}

For building owners, the economic benefits are assessed from the perspective of lower connection charges, lower monthly power charge, lower capital cost, and reduced system losses. The non-financial benefit of improved power quality and reliability is also considered. For the grid operator, it is assessed from the perspective of cheaper generation costs and deferment in system upgrading costs. These benefits are derived from reducing the electrical load variability as a result of load shifting. As the electrical loads are varying constantly, the output of power plants need to be varied to meet the changing load and this reduces the efficiency. Furthermore, the capacity of the electrical power system needs to cater for the peak load, which occurs only for a short duration. Hence, reducing load variability will improve the efficiency and reduce wastage. In this study, it is found that substantial saving is obtained by shifting the top 3% peak load while carbon emission is reduced. The maximum saving obtained by the building owners and grid operator is USD 0.47 and USD 3.59 per kWh.","PeriodicalId":134414,"journal":{"name":"2015 International Conference on Smart Grid and Clean Energy Technologies (ICSGCE)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114649941","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}

Although real-life M Bus networks can reach a significant size and complexity, there are only very simple protocol analyzers available. Therefore developers and installers do not have an easy and low cost possibility to analyze real bus signals. This led to the design and implementation of a web-based monitoring tool for the M Bus together with a physical bus interface to measure and records the bus signals. Therefore, in the first place a circuit was designed, which transforms the voltage and current modulated M-Bus signals to a voltage signal, which can be read out by a standard Analog-Digital-Converter (ADC). Once captured, the bus signals are displayed using a web server, which furthermore analyzes and classifies the frame fragments. As an additional feature an oscilloscope functionality is included into the tool. This makes the analyzer a powerful tool with high compatibility and flexibility. This contribution concentrates on the development of an interface circuit to read the Wired M-Bus and how the data can be regained. This article describes the general concepts from the design of the M-Bus sniffer as well as some details about the implementation and the underlying signal processing. The implementation is divided into two major parts: The implementation of the Sniffer-Driver both in hardware and software and the adaption of this driver to an existing head unit including the user interface.","PeriodicalId":134414,"journal":{"name":"2015 International Conference on Smart Grid and Clean Energy Technologies (ICSGCE)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122149640","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}

But the method suffers from the problems of oscillations around the maximum power point (MPP) during the steady state. Various methods have been reported in the literature to overcome the problem of oscillations around the MPP in the steady state. These methods perform well in the regions with uniform irradiance from the sun throughout the day. However, in the regions with highly variable irradiance due to stochastic cloud cover and cyclonic activity, the P&O based MPPTs with no steady state oscillations do not operate properly due to their slow response to the changing irradiance. This paper proposes a P&O based MPPT which tracks the MPP of a PV module in the face of varying irradiance. Simulation results show that the proposed algorithm quickly tracks the MPP. The results also show that the proposed method has 99.92% efficiency in the steady state operation. The proposed algorithm is simple to implement as no additional hardware is required for its implementation.","PeriodicalId":134414,"journal":{"name":"2015 International Conference on Smart Grid and Clean Energy Technologies (ICSGCE)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121719033","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}
