Abstrakt: In Korea, reduction of nuclear power and coal power generation equipment and expansion of renewable energy were planned according to the renewable energy 3020 plan. It is planned to expansion of the renewable generation that amount to 20% of the total power generation by 2030. So it is necessary to build the future power system Database(DB). This paper describes the construction of future power system DB according to expansion of renewable. DB construction, system stabilization and stability analysis are performed automatically by using python-based simulator. The simulator is linked to the PSS/E, the power system analysis tool, through the application programming interface. Algorithm modeling is carried out about system DB construction and stability analysis for generating simulator. And about the PSS/E initial DB construction method of the power system raw data through the generated simulator will be described. First, construction a topology composed of existing generators without renewable sources and stabilize the power flow. And then describe the addition of a renewable generator and a method for power system analysis and stabilization of the constructed initial power system. This paper describes the modeling of renewable energy source and the control of shunt and the addition of FACTS devices for stabilize the power flow. And Transformer Tap ratio adjustment method for stabilizing grid bus voltage are described. Fault analysis is performed to check whether the fault current exceeds the allowable range according to being added of the renewable energy source. In addition, we describe a steady-state and contingency accident state analysis simulator. and describe method to overcome line overload. In this paper, we describe the line linkage method by calculating WSCR index. Once the powerflow convergence, line overload and fault analysis are completed, dynamic analysis stimulation is described. It will be checked the stability of the system by checking the initialization of the dynamic stimulation and the divergence of the result graph. [ABSTRACT FROM AUTHOR]
