Abstract: This paper aims to identify and clarify the cyber security risks and their interaction with the power system in Smart Grid. The SCADA system and other communication networks interact with the power system on a real time basis, so it is important to understand the interaction between two layers to protect the power system from potential cyber threats. In this study, the optimal power flow (OPF) and Power Flow Tracing are used to assess the interaction between the SCADA network and the power system. Through OPF and Power Flow Tracing based analysis, the physical and economic impacts from potential cyber threats are assessed, and thereby the quantitative risks are measured in a monetary unit.

Abstract: The governments of US, Japan, Europe are planning overall change of electrical power system by adapting Smart Grid as a solution of increasing demand of electricity every year. Especially, ESS have been actively studied to plan efficient use of electrical power and grid-connected. Korea government have been proceeding not only plan of renewable energy but also spread of smart grid. At the same time they have been discussing introduction of ESS which is effective solution of demand response and new growth power. In this study, according to K-ESS policy which is governmental policy of popularizing ESS. we suggest REC weighting value control among the a lot of supporting method that if renewable Genco apply ESS system they would not suffer from lose. It is meaningful because it could be referred to the way of offering governmental incentive for the purpose of decrease peak level and enhance the contribution level of peak.

Abstract: With the rapid development of the power industry, there has been more and more large thermal power unit which is more than or equal to 600MW , steam turbine equipment gradually tend to be high parameter, large capacity, complicated, the overhaul maintenance to steam turbine is the main content of the power plant production activities, it directly affects the reliability of the coal-fired power plant production safety. Aimed at the complexity of thermal steam turbine overhaul, by the use of advanced interactive devices on the visual, do an auditory perception of the virtual environment for something, which is helpful to improve practical operation skills. This paper examines the necessity and superiority of this system applied in education and training. Taking 3-D dynamic simulation system of building as an example, this paper discussed how to utilize the SolidWorks2012 and VRP - SDK to build a virtual training system, realized the combination with virtual reality and education training ,also greatly promoted science and technology progress，equipment of the steam turbine overhaul industry.
