英文要約Title: Japan-U.S. Smart Grid Collaborative Demonstration Project (FY2010-FY2011) FY2010 Annual Report

We are mainly focusing on (1)Microgrid Demonstration in Los Alamos, (2)Microgrid Demonstration in Commercial Areas in Albuquerque, (3)Collective Research on a Smart Grid, (4)Research on cyber security and information and (5)Development of model simulation techniques. (3), (4) and (5) are parts of Collective Research on Overall Project. : Regarding (1) and (2), we have designed the most functions of Micro EMS and MDMS. Especially for (1), we have also designed the IT network environment achieving the secure access from Japan. Now, we will finish the engineering for the battery and PV construction in LAC site. The construction for battery and PV sites will start at September 1st and November 1st, 2011, respectively. : Regarding (3), we modeled distribution power system and Smart Grid (SG) equipment, and performed simulation study on LAC SG for confirming validity of equipment capacities and for studying islanding operation sequences. In order to evaluate SG functions and performances by using demonstration experimental data, we investigated evaluation indexes and reflected it to Data Management System design. For total evaluation of SG through comprehensive simulation study, we modeled simple external power system by short-circuit impedance, and have performed system design of simulation platform and developed simple demand-control simulator for example. : Regarding (4), we are discussing 3 topics, 1) Privacy protection for metering data, 2) Robust protocol against brute force authentication attack and 3) Cyber security testing framework. For 1), we investigated MDMS privacy protection scheme which protect metering data from an attack from malicious user or improper user. We also investigated an evaluation technique for the privacy protection scheme. For 2), we investigated how to apply light-weight message authentication technique over network transport layer which can prevent DDoS attacks to the smart grid modules with other security standard protocols, and designed the combined protocol. For 3), we identified logical function diagram and surveyed standard candidates applied to the LAC micro-grid system. Based on the diagram and the standards, we investigated identification of critical assets. : Finally, regarding (5), we have developed a demand simulator for residential house. The demand simulator consists of human behavior model, home appliance model, PV model, battery model, HEMS model. We have simulated a Japanese house with 4 people. 24 hours simulation time of 1 house was around 3 seconds and simulation for 1000 houses was estimated to be around 50 minutes. We have also developed demand simulator's interface to distributed grid simulator for power flow analysis.
