“…The possibility for real-time simulation was first demonstrated on the NCube2 HypeCube [233]. HyperCube machines were popular in the early 90s for transient studies exhibiting various techniques such as SOR [234] and LU factorization path trees with different communication scheduling techniques [235] [90].…”

“…eMEGASIM offers a direct platform compatible with ePHASORSIM, which procure maximum versatility from a large power grid simulation to highly detailed power electronic simulation. ePHASORSIM allows the simulation of massive grids going up to 20k buses on a single core computer and its capability to perform parallel computing allowing unleashed performances for lager realtime simulation [31], [32], [33], [34], [39]. The typical time step of these two systems is displayed by Fig.4.…”

This paper proposes two methods to improve the performance in real-time simulation. The increased inverter-based generations are gradually shifting the operation of the power grid. Consequently, the investigation for the safe operation and further application is essential in the inverter-dominated power grid. As the simulated number of non-linear switch elements like inverter increases, the numerical complexity of the simulation model rises exponentially. Accordingly, the scale of the simulated power grid with inverters is normally constricted by taking account of the burdensome numerical calculation. The emerging of realtime simulator provides the opportunity to enable the simulation of the large-scale power grids. Nevertheless, the simulation boundary condition is still exceeded in the inverter-dominated model. Hence, the improvement of the performance to extend the limitation in real-time simulation is constituted in this paper. The first method proposed is co-simulation. This approach is to simulate the power grid and inverters by models in different deep levels. The phasor model and electrical-mechanical-transient model are utilized to develop the co-simulation model. The second method is network reduction. Based on the dynamic feature of the inverter, it is reduced to an equivalent current source, which decreases the complexity of the model and retains its characteristics. The evaluation of the methods is demonstrated by two indexes: real-time capability and the similarity degree.

EMS design has traditionally been a top-down process, in which a single vendor provides the algorithms, software and hardware to meet the utility's functional specifications. Recent trends in power systems, such as the move by utilities to Open Systems architectures, and the development of distributed computing systems indicate that this process must be changed to incorporate the new expertise required in EMS design. We propose an Open Design Approach to accomplish this. Our design approach is based on decomposing the EMS design problem according to different levels of abstraction. We define the components of this decomposition and discuss their relationships. These components form the conceptual design for a CAD simulation package which is being developed at UC Berkeley to evaluate and compare the performance of alternative designs.
