These two properties, although functional and practical, expose the grid to overload and consumption forecasting uncertainty. In addition, the distribution of electricity may be difficult to manage; sudden demand surge or supply shortage may ultimately lead to failures. To overcome this, we adopt a recently proposed approach whereby electricity is delivered in discrete amounts, through what is named here as a controlled-delivery power grid. In this grid, the customer's addresses are embedded in the electrical signal, and smart loads are used to limit the supplied electrical power. These smart loads not only control the consumed amount of power but also provide reactive stability to the distribution loop. We discuss an architecture of the controlled-delivery power grid and analyze a management scheme for the distribution of power, where the capacity of the distribution loop is capped to the average of the requested power, adopting a round-robin schedule of power deliverance. We show that the efficiency of power distribution satisfies over 98% of the power requests in such scenarios of energy scarcity.","PeriodicalId":136434,"journal":{"name":"2013 IEEE International Conference on Smart Grid Communications (SmartGridComm)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115789183","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}

A novel aspect of our approach is the ability to predict the customer response to price incentives that are designed to induce shifts in the electricity usage from the peak to the off-peak time periods of the daily residential load cycle. A Multinomial Logit (MNL) consumer-choice model is used for estimating the magnitudes of these intra-day hourly loads. The resulting nonlinear optimization problem for the specified profit and capacity-utilization objectives is solved using a series of transformations, which include the reformulation-linearization technique (RLT), to obtain a Mixed-Integer Programming (MIP) model. Using a piecewise-linear cost structure for satisfying electricity demand, we subsequently derive a set of valid inequalities to effectively tighten the underlying relaxation of this MIP. The proposed optimization methodology can also incorporate various regulatory and customer bill-protection constraints. Our model calibration and computational analysis using a real-world data set indicates that the proposed predictive-control methodology can be incorporated into a practical decision support tool to manage the time-of-day electricity demand in order to achieve the desired objectives.","PeriodicalId":136434,"journal":{"name":"2013 IEEE International Conference on Smart Grid Communications (SmartGridComm)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122624283","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 a micro grid system, management of supply and demand is one of the most important issues because variability of renewable energies such as photovoltaic and wind power generations will cause a supply-demand imbalance. Management of supply and demand in direct current (DC) power networks is supposed to be more difficult in comparison with conventional methods for alternate current (AC) power networks. The reason why is that a delay in the conversion of DC to DC and AC to DC causes unintended power down in DC power networks without huge power supply such as grid power in AC power networks. In this paper, we propose an energy management method for DC power networks. A control system which realizes the proposed energy management consists of a two-layered structure. The first layer is a scheduling part which is responsible for deciding the long-period system behavior to reduce energy bills. The second layer is a supply-demand adjustment part which is responsible for maintaining instantaneous supply-demand balances for DC-driven devices. The effectiveness of the proposed method has been proven with some experiments using real equipment.","PeriodicalId":136434,"journal":{"name":"2013 IEEE International Conference on Smart Grid Communications (SmartGridComm)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126567913","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}

Many of the scenarios manifest as equipment failures caused by physical damage, interruption of communication networks, and/or mis-feeding of information. Conventional power systems are designed to be robust to accidental failures. Nevertheless, under the post 9/11 environment, coordinated multiple strikes become a realistic threat. Therefore, an online system for multiple attacks detection, recognition, and localization is essential for providing accurate information to control and actuation. In this paper, we propose a novel conceptual framework, referred to as “event unmixing”, for the online analysis of multiple attacks, where we interpret the disturbance caused by multiple attacks as a linear mixture of more than one constituent root faults. By incorporating temporal stamps into the construction of an overcomplete dictionary, consisting of patterns of different root faults, we are able to detect, recognize and identify the starting time of each fault based on the concept of “event unmixing”. This is followed by the fault localization process by utilizing the starting time of each individual fault detected at different sensors based on the triangulation method. The proposed framework has been evaluated using both PSS/E simulated data and real data collected from the frequency disturbance recorders (FDRs) of the Frequency Monitoring Network (FNET). The experimental results demonstrate the effectiveness of the proposed framework for analysis of multiple attacks.","PeriodicalId":136434,"journal":{"name":"2013 IEEE International Conference on Smart Grid Communications (SmartGridComm)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127654454","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}
