lightweight security and privacy preserving scheme for smart grid Customer Side networks
IEEE Transactions on Smart Grid, 2017Co-Authors: Asmaa Abdallah, Xue Min ShenAbstract:Information security and Customers’ privacy in smart grid are significant concerns. Existing security and privacy preserving schemes conSider that the consumption reports for electricity consumption aggregation and billing purposes are sent periodically. These periodic messages increase the computation and communication burden on restricted-capabilities smart meters. In this paper, we propose a lightweight security and privacy preserving scheme that is based on forecasting the electricity demand for a cluster of houses in the same reSidential area; it limits the cluster’s connection with electricity utility only when the cluster needs to adjust its total demand. The scheme efficiently satisfies the security and privacy requirements in Customer-Side networks, i.e., communication between Customers and power utility. At the same time, it significantly reduces the communication and computation overhead. Moreover, the proposed scheme utilizes NTRU cryptosystem to further reduce the computation complexity.

analyzing and improving Customer Side cloud security certifiability
International Symposium on Software Reliability Engineering, 2019Co-Authors: Shujie Zhao, Yiqun Chen, Stefan Winter, Neeraj SuriAbstract:Cloud services have become popular as an effective form to outsource computational resources. While providing cost efficiency on the one Side, this outsourcing also causes a certain loss of control over the computational resources, which makes security risks difficult to predict and manage. To address such concerns, security service level agreements (secSLAs) have been proposed as contracts between Cloud service providers (CSPs) and Cloud service Customers (CSCs) that cover security properties of Cloud services. SecSLAs cover a variety of different security properties, ranging from the availability of encrypted communication channels for accessing Cloud resources to the timely detection and removal of vulnerabilities in the CSP's infrastructure. As previous work [1] has shown, and as is evident for the example of timely vulnerability removal, not all of these security properties can be assessed by the CSC, which limits their utility as a contract basis. In this paper we propose a new monitoring framework for Cloud services to support the monitoring and validation of security properties on the Customer Side that require infrastructure-internal knowledge. To obtain the security properties to be monitored by our framework, we have manually investigated 97 different quantifiable properties in 5 standards from both industry and academia. We identified only 21 measurable properties from those standards, out of which we implement measurements for 13 representative ones and evaluated our measurements on the OPENSTACK platform.

Economic evaluation of demand‐Side energy storage systems by using a multi‐agent‐based electricity market
Electrical Engineering in Japan, 2009Co-Authors: K Furusawa, H. Sugihara, Kiichiro TsujiAbstract:With the wholesale electric power market opened in April 2005, deregulation of the electric power industry in Japan has faced a new competitive environment. In the new environment, Independent Power Producer (IPP), Power Producer and Supplier (PPS), Load Service Entity (LSE), and electric utility can trade electric energy through both bilateral contracts and single-price auction at the electricity market. In general, the market clearing price (MCP) is largely changed by the amount of total load demand in the market. The influence may cause a price spike, and consequently the volatility of MCP will make LSEs and their Customers face a risk of higher revenue and cost. DSM is attractive as a means of load leveling, and has an effect on decreasing MCP at peak load period. Introducing Energy Storage systems (ES) is one DSM in order to change demand profile at the Customer Side. In the case that Customers decrease their own demand due to increased MCP, a bidding strategy of generating companies may be changed. As a result, MCP is changed through such complex mechanism. In this paper the authors evaluate MCP by multi-agent. It is conSidered that Customer-Side ES has an effect on MCP fluctuation. Through numerical examples, this paper evaluates the influence on MCP by controlling Customer-Side ES corresponding to variation of MCP. © 2009 Wiley Periodicals, Inc.

a study on power flow congestion relief in cooperation with Customer Side cogeneration systems
Electrical Engineering in Japan, 2008Co-Authors: K Furusawa, H. Sugihara, Kazunori Yanase, Kiichiro TsujiAbstract:Dispersed generation technologies (e.g., gas engines) have greatly advanced in recent years. Gas engines are often operated as the main component of a cogeneration system (CGS). By using exhaust heat, the total efficiency of CGSs can reach from 70% to 80%, and as a result, it is also useful for reductions of CO2 emission. Therefore, CGSs have been given preferential treatment by the Japanese government and their installation and use is expected to become widespread in the future. When Customers introduce CGSs, these systems have an influence on the demand profile for electric utilities. On the other hand, CGS operational patterns depend on Customers' economic requirements; thus, it is difficult to flexibly change those patterns so that they meaningfully contribute to the electric utility. As a demand response program, the authors proposed a method whereby CGSs at the Customer Side are used for congestion relief in transmission networks. In the proposed method, the optimal configuration of energy systems including CGSs at the Customer Side is determined. As well, the optimal operation of the electric utility's generators is also determined taking into account the CGS operation patterns. This paper evaluates both costs to the electric utility and the Customers' cost for congestion relief in transmission networks. Further, we evaluate the influence on CO2 emission and primary energy consumption from the viewpoint of a unified energy system with CGSs providing input on a flexible operation pattern. © 2008 Wiley Periodicals, Inc.

Power flow congestion relief by using Customer-Side energy storage systems
Electrical Engineering in Japan, 2007Co-Authors: K Furusawa, H. Sugihara, Kiichiro Tsuji, Yasunori MitaniAbstract:In recent years, energy storage systems have increasingly been expected as a means of load leveling of the annual load factor. Of course there is an effect of installing the energy storage systems at the substation. But some Customers operate their storage system in an integrated way and it also has an effect of increasing the load factor. In this paper the authors proposed that the energy storage systems on the Customer Side be used for congestion relief on transmission networks. However, it is not clear which kind of Customer has the effect of relieving transmission line congestion. First, this paper assumes the authors determine the optimal configuration of energy equipment including energy storage systems. We propose a new contract whereby electric utility subsidizes a part of the entrance cost of the energy storage systems and Customers change the output pattern of energy storage according to the request of the electric utility. This paper evaluates the possibility that the contract gives merit to both the electric utility and the Customer. © 2006 Wiley Periodicals, Inc.

A cooperation with Customer-Side cogeneration systems for power flow congestion relief and its environmental impact
2006 IEEE Power Engineering Society General Meeting, 2006Co-Authors: K Furusawa, Kenji Yanase, H.
