“…Recent studies on speeding up power system simulations fall into two categories: 1) utilization of parallel computing via parallel-in-space methods such as the multi-decomposition method [7], domain decomposition method in [8] [9], and multi-area Thé venin equivalents in [10], or parallel-in-time methods such as the waveform relaxation method in [11] and Parareal method in [12]- [19]; and 2) semi-analytical simulation methods such as the Adomian decomposition method in [20] [21], time-power series method in [22], differential transformation method in [23] [24], and holomorphic embedding method in [25].…”

For parallel-in-time simulation of large-scale power systems, this paper proposes a differential transformation based adaptive Parareal method for significantly improved convergence and time performance compared to a traditional Parareal method, which iterates a sequential, numerical coarse solution over extended time steps to connect parallel fine solutions within respective time steps. The new method employs the differential transformation to derive a semi-analytical coarse solution of power system differential-algebraic equations, by which the order and time step, as well as the window length with a multi-window solution strategy, can adaptively vary with the response of the system. Thus, the new method can reduce divergences and also speed up the overall simulation. Extensive tests on the IEEE 39-bus system and the Polish 2383-bus system have verified the performance of the proposed method.

Very recently, a new transient stability methodology referred to as the Localized Transient Stability (LTS) Method was proposed solely for the purpose of realtime localized control of transient stability. The method is based on a completely new idea of localized transient stability. In this paper, real-time localized control of transient stability by the LTS method is described. Since the technique is based on the LTS method, transient stability in this technique is viewed as the interaction of each individual generator with its respective remaining generators. Therefore, in this technique, the post-fault power system is represented by a two-generator localized power system at the site of each individual generator. Each of these localized power systems is then driven to its respective stable equilibrium by local control actions with local computations using the locally measured data in order to drive the full (entire) power system to its stable equilibrium. New investigative results are presented with Static Synchronous Series Compensator (SSSC) as the local control means to demonstrate the potential of real-time localized control of transient stability by the LTS method.  Index Terms-localized power system, localized transient stability, real-time localized control, transient stability

<p>Very recently, a new methodology was introduced solely for the purpose of real-time localized control of transient stability. The proposed new method is based on the localized transient stability of a power system. This is completely a new idea in transient stability. In this method, the post-fault power system is represented by a two-generator localized power system at the site of each individual generator. If each of these localized power systems reaches its respective stable equilibrium, then the full power system also reaches its stable equilibrium. Therefore, in terms of real-time localized control of transient stability, if each of the localized power systems is driven to its respective stable equilibrium by local control actions with local computations using the locally measured data, then the full power system is driven to its stable equilibrium. Thus the method can be easily implemented for real-time localized control of transient stability. In this paper, the details of the mathematical formulations are presented. Some interesting test results on the well-known New England 39-bus 10-generator system are also presented in this paper to demonstrate the potential of the proposed method for use in real-time localized control of transient stability.</p><p> </p>
