Based on findings for grid planning principles for EVs, an approach was explored to reduce grid loads caused by charging currents through the reduction of the probability of simultaneous charging cycles. Through the implementation of a split charging routine, which limited the first residential charge to a maximum state of charge, the corresponding reduction in charging duration translated into a reduced coincidence factor. Furthermore, the remaining charging capacity was made accessible as a flexible load for an aggregator. In order to prevent price-triggered high coincidences, these aggregators were integrated into the German \"Grid Traffic Light\" concept to allow for optimal load distribution. Here, based on the Quota System developed by the Netze BW, it was shown, that both markets and grid operators benefited from this approach.","PeriodicalId":330869,"journal":{"name":"2016 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe)","volume":"19 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":"130815143","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}

Similarly to the traditional power systems, state estimation algorithms are necessary in AC/DC grids to acquire awareness about the operating conditions of the system and to enable proper operation of the control tools. This paper presents a state estimator tailored for hybrid AC/DC grids with multi-terminal dc grid configuration. The proposed estimator is based on a two-step algorithm, which uses the boundary results of the AC and the DC grid to enhance the accuracy of the estimation. Results on a simple test network are presented to show the validity of the proposed estimator and to highlight the inherent benefits.","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":"131079632","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}

Due to the uncertainty of the DG output, it becomes extremely difficult to control the system voltage profile. This paper proposes a coordinated decentralized voltage control method, together with a self-excited inverter, that can control the voltage level by reactive power injection/absorption. The time-delay introduced by communications among DGs is considered to validate the proposed control approach. Simulation results show that the coodinated control approach is sensitive to the time-delay in a 33-bus medium-voltage distribution network (MVDN).","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":"123184755","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}

We apply the idea of linear error-correcting block codes, which has originally been used in detecting and correcting errors in data transmission, to detect and correct customer attacks aimed at changing the readings of smart electricity meters. We propose to use these codes, with some modifications, in order to detect and correct deceptive readings of a group of electricity meters measuring the energy delivered by cablesfeeders fed from the same nodebus. We start by considering a single meter attack, and we show that the detection and correction of a single attack in the readings of 2m — M — 1 meters, connected to cables fed from the same node, requires only using M current transformers in addition to knowing the voltage at the common node. We demonstrate the theoretical implementation of this coding scheme, and then we discuss some practical challenges and their proposed solutions. Furthermore, extension to multi-error correcting codes, which are capable of detecting and correcting several simultaneous deceptive readings of a group of meters, is also discussed.","PeriodicalId":330869,"journal":{"name":"2016 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe)","volume":"14 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":"127801357","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}

This study applies linear decision rules-based (LDR) control policies, which effectively adapt the present participation factor in dependence of the imbalance signal of previous time steps. The LDR-policies are centrally computed using a robust optimization approach which takes into account both the covariances of historic imbalance signals and the operational flexibility of ancillary service providers. The concept is then extended to the cooperation of multiple cells.

A charge controller is used to protect the battery from overcharging and to control the overall system operation.

Different from other formulations, decision variables are associated with phasor measurements, but not with PMUs. This approach makes it easy to take into account the availability of PMU measuring channels, effect of zero-injection bus, possible system contingencies like single PMU or branch loss, as well as gross error occurrence, and offers flexibility in specifying the objective function. Paper describes a presolve technique that makes the formulation more compact and tighter.

Making demand response available on the wholesale market on a large scale is a challenge. Retailers and aggregators, providing services to individual consumers as well as bringing aggregated flexibility to the wholesale market, is foreseen to play important roles in this respect. This paper presents a aggregator decision support model for demand scheduling, including demand response and purchase bid optimization for day-ahead markets. Income from providing electricity to consumers, and costs related to imbalances, rescheduling and energy not served are also considered. The model includes risk management by applying the conditional value-at-risk risk measure.
