| Abstract |
In response to the increase in renewable energy sources, large-scale Energy Storage Systems (ESS) are being deployed in the power grid. When power facilities composed of large-scale plants are connected to the grid, it is necessary to verify detailed engineering assessment and grid code compliance. To successfully conduct these evaluations using power system analysis programs, detailed modeling of the ESS plant is required. This paper presents the development of a User Defined Model (UDM) for ESS plant controllers, which is essential for performing engineering assessment and assessing grid connection code of ESS plants using PSS/E, a large-scale power system analysis program. Through various case studies, it was verified that the control performance required by grid connection code could be achieved by regulating the power based on a Point Of Interconnection (POI) by the plant controller, which manages multiple inverters in the ESS plant. |
