Abstract
There is an increasing trend in power consumption and integration of renewable energy resources in the existing electric grid infrastructure. These demands cause a great amount of stress in the power grid and lead to its instability. Such instability can quickly spread across the power grid and cause power blackouts in large areas. Remedial Action Schemes (RAS) are intended to provide wide-area monitoring, prevention and remediation of power grids against extreme events that lead to blackouts [SHA+14]. Given the importance that RAS play in maintaining the stability and reliability of power grids, it becomes extremely important to make sure that each RAS is operating correctly at all times [NERC07]. Erkios 0.1 [Cha14] was developed to fill in this gap by providing in-field testing of RAS. The focus of Erkios 0.1 work was defining the architecture and failure model for Erkios. This was the necessary step towards providing in-field testing of RAS. Erkios 0.2 is the improved version of Erkios 0.1 which is capable of testing different kinds of RAS that are dependent on the topology of power system they are intended to protect. For Erkios 0.2, we implement a RAS for a 10-bus 2-area power system to be used as a test case to demonstrate the feasibility of Erkios 0.2 in testing real-world RAS. Additionally, we have added an implementation of the emulation logic for different contingencies so that Erkios 0.2 can test the RAS for different kinds of contingencies. We show how Erkios 0.2 works well with RAS and provides its testing when the RAS is in-field. Further, we architect the future integration of Erkios with power equipment (like SEL R-TAC and SEL 421 PMU). We have designed the architecture for the integration of Erkios with the testbed based at Smart Grid Demonstration and Research Investigation Lab (SGDRIL) that will serve as the blueprint for the actual integration process in future between the Erkios software and power equipment hardware.
