Nevertheless, it is also important to maintain the integrity of aggregate data in the presence of accidental errors and internal/external attacks. To ensure the correctness of the aggregation against unintentional errors, we introduce an end-to-end signature scheme, which generates a homomorphic signature for the aggregation result. The homomorphic signature scheme is compatible with the in-network aggregation schemes that are also based on homomorphic encryption, and supports efficient batch verifications of the aggregation results. Next, to defend against suspicious/compromised meters and external attacks, we present a hop-by-hop signature scheme and an incremental verification protocol. In this approach, signatures are managed distributedly and verification is only triggered in an ex post facto basis - when anomalies in the aggregation results are detected at the collector. The incremental verification process starts from the collector, and traces the anomaly in a breath-first manner. The abnormal node is identified within O(logN) iterations. Therefore, the verification process is computationally inexpensive, while ensuring faithfulness and undeniability properties.","PeriodicalId":143915,"journal":{"name":"2012 IEEE Third International Conference on Smart Grid Communications (SmartGridComm)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115372564","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}

On the other hand, over the past several years, there has been a growing interest for the utility companies to integrate more renewable energy resources. Such renewable resources, e.g., wind or solar, due to their intermittent nature, brought great uncertainty to the power grid system. In this paper, we propose a mechanism that attempts to mitigate the resulting grid operational uncertainty by properly exploiting the potentials offered by demand flexibility. To address the challenge, we develop a novel locational marginal price (LMP) based pricing scheme that involves active demand side participation by casting the network objectives as a two-stage Stackelberg game between the local grid operator and several aggregators. We use the solution concept of subgame perfect equilibrium to analyze the resulting game and derive the optimal pricing scheme. Subsequently, we discuss the optimal real time conventional capacity planning for the local grid operator to achieve the minimal mismatch between supply and demand with the wind power integration. Finally, we assess our proposed scheme with field data. The simulation results further confirm the optimality of our scheme and suggest reasonably well long term performance with simplified heuristic approaches.","PeriodicalId":143915,"journal":{"name":"2012 IEEE Third International Conference on Smart Grid Communications (SmartGridComm)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125580825","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}

Two types of control, a distributed proportional control and a centralized integral control, are currently used to keep frequency deviations small. Although generation-load imbalance can be very localized, both controls primarily rely on frequency deviation as their input. The time scales of control require the outputs of the centralized integral control to be communicated to distant generators every few seconds. We reconsider this control/communication architecture and suggest a hybrid approach that utilizes parameterized feedback policies that can be implemented in a fully distributed manner because the inputs to these policies are local observables at each generator. Using an ensemble of forecasts of load and time-intermittent generation representative of possible future scenarios, we perform a centralized off-line stochastic optimization to select the generator-specific feedback parameters. These parameters need only be communicated to generators once per control period (60 minutes in our simulations). We show that inclusion of local power flows as feedback inputs is crucial and reduces frequency deviations by a factor of ten. We demonstrate our control on a detailed transmission model of the Bonneville Power Administration (BPA). Our findings suggest that a smart automatic and distributed control, relying on advanced off-line and system-wide computations communicated to controlled generators infrequently, may be a viable control and communication architecture solution. This architecture is suitable for a future situation when generation-load imbalances are expected to grow because of increased penetration of time-intermittent generation.","PeriodicalId":143915,"journal":{"name":"2012 IEEE Third International Conference on Smart Grid Communications (SmartGridComm)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130389705","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 a smart grid communication system, the requirements for stability, security and reliability are more strict than those for other M2M applications. Interference management is one of the key challenges to ensure the wireless system working with stability and reliability. The interferences may come from the existed SCADA (Supervisory Control and Data Acquisition) system, or some unknown devices using the same spectrum band occasionally. In this paper, we propose a novel mechanism for a WiMAX based system to manage various in-band interferences under cognitive environment, which are meaningful when there is no dedicated spectrum resource assigned for the new system or at the stage for system evolution from narrow band to broadband. We design the periodical sensing (PS) process during the normal wireless communication to obtain the realtime interference information and define the cross layer message between PHY and MAC to deliver the interference information to downlink and uplink respectively. Based on the time and frequency domain analysis for PS data, we classify received interferences into several types and execute corresponding management methods to reduce the influences caused by interferences. Through the field test in two cities, it proves that the interference management mechanism we proposed is effective.","PeriodicalId":143915,"journal":{"name":"2012 IEEE Third International Conference on Smart Grid Communications (SmartGridComm)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131969675","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}
