Electricity storage plants can provide flexibility to the energy system and the development of new, efficient and economical energy storage technologies is of great importance. In this paper, the use of compressed air energy storage plants in the German electricity market is simulated and a sensitivity analysis is carried out. The optimization of the system is done to minimize at each time step the total system costs. The analysis shows the influence of storage plant parameters such as efficiency, storage capacity and natural gas usage on the dispatch and operation hours. It is performed over one year and for three different future scenarios. The results indicate that utilization of storage plants will increase in each scenario considered from 2025 to 2035 but remains in most cases significantly below the maximum capacity of 3000 h/a power generation. While the operation of storage plants lowers the total electricity cost, earnings per plant and profits are not necessarily positive: the wholesale price signals do not create enough revenues to justify the investment in CAES plants.","PeriodicalId":330869,"journal":{"name":"2016 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126922302","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}

Identification of such lines in a meshed multi-compensated power network is not possible through mere topological inspection. The paper presents a methodology for identifying Critical lines that may be hidden in meshed networks and can be used by the System Operator to raise EMS alarms against SSR threats in case of planned or unplanned outages. The paper also describes how Wide Area Monitoring Systems (WAMS) can be used to provide an economical alternative to existing SSR mitigation techniques by making best use of existing WAMS assets and minimizing further investment. To provide visibility of torsional oscillations (4–46 Hz), the paper describes a new Waveform Measurement Unit (WMU) that offers this additional functionality using a software update of a contemporary PMU, which is being trialed for the first time as part of the GB VISOR project. The potential opportunity and challenges of using WAMS for SSR mitigation is studied using the IEEE FBM. The methodology for identifying Critical lines and generators is demonstrated using the IEEE 68 bus model.","PeriodicalId":330869,"journal":{"name":"2016 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126199540","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}

Consequently, the amount of available PQ data is also growing very fast. These data contain a lot of valuable information about the behavior of PQ, but up to now it is in the most cases used only to assess compliance with limits (e.g. EN 50160 in Europe). Beside long-term characteristics (trends) and medium-term characteristics (seasonal effects) in particular the analysis of short-term characteristics can provide useful information about deviations from a \"typical\" behavior, which are usually caused by significant changes in the customer or network behavior (e.g. connection of new disturbing equipment). As manual screening of the data is not feasible, automated methods to identify such \"anomalies\" are required. After a short description of typical variations in PQ datasets the paper classifies different types of anomalies in PQ time series and presents a new method in order to identify them. Finally, the performance of the method is discussed based on examples.","PeriodicalId":330869,"journal":{"name":"2016 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131306658","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}

In contrast to this well-studied occurrence, we report here on the emergence of novel synchronized behaviors of thermostatically-controlled electric heating systems in buildings with good thermal insulation and important solar radiation gains without DSM. To suppress the resulting large load fluctuations on the distribution grid we propose a centralized DSM algorithm that smoothens the total load curve — including electric heating and all other domestic appliances — of the cluster of dwellings it pilots. Setting up the baseline load is based on weather forecasts for a receding time-horizon covering the next 24 hours, while control actions are based on a priority list which is constructed from the current status of the dwellings. We show numerically that our DSM control scheme can be generically used to modify load curves of domestic households to achieve diverse goals such as minimizing electricity costs, peak shaving and valley filling.","PeriodicalId":330869,"journal":{"name":"2016 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134118165","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 new generation installed at the consumer premises may induce voltage problems while the loading of the cables is still under nominal values. Conventionally possible resulting voltage violations are solved by reinforcing the network, however smart grid alternatives like voltage control in the LV network can also alleviate the network problems. LV-networks are traditionally designed with medium to low voltage transformers equipped with off-line tap changers. The addition of an on-load tap changer (OLTC) for voltage control can decrease the voltage violations in the network, however this needs to be considered within the optimisation method applied for the planning of the LV-network. In this paper the smart grid alternative of installing an OLTC in this optimisation has been performed. By assessing different OLTC control strategies under conditions with increasing distributed generation over many types of networks, the effectiveness of the OLTC becomes apparent. The OLTC is included in the optimization problem formulation by the introduction of additional voltage constraints and relaxing the constraints in the form of a penalty function. When the introduction of an OLTC is more efficient rather than the conventional strengthening of the network is demonstrated with a case study on the impacts of distributed generation.","PeriodicalId":330869,"journal":{"name":"2016 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122855573","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}
