“…The aims of this case are to show an application of the model and to evaluate its performance. Figure 2 shows all non-synchronous generators and the location of the fault, which is a direct 3-phase short circuit at bus 16 cleared after 300 ms by the disconnection of line [15][16]. A GAMS model corresponding to this case is provided as a separate file in [33].…”

“…Given the size and complexity of TSCOPF optimization models, the necessary trade-off between model detail and computational time has produced a number of different approaches [13]. Numerical methods that incorporate the discretized differential equations defining the dynamics of the power system into the formulation of the OPF [14,15] have several advantages, such as being able to robustly handle unstable systems with different constraints [13]. However, they produce large models with a number of variables and equality constraints that is impractical for large or medium-size systems.…”

Abstract:The increasing penetration of non-synchronous, renewable energy in modern power systems displaces synchronous generation and affects transient stability. This is just one of the factors that has led to preventive curtailment of renewable energy sources in an increasing number of electrical grids. Transient stability constrained optimal power flow (OPF) techniques provide a tool to optimize the dispatch of power systems while ensuring a secure operation. This work proposes a transient stability-constrained OPF model that includes non-synchronous generation with fault ride-through capability and reactive support during voltage dips. The model is applied it to the IEEE 39 Bus benchmark test case and to the power system of the Spanish island of Tenerife, and solved using the open-source library IPOPT that implements a primal-dual interior point algorithm. The solution of the model makes it possible to optimize the dispatch of conventional plants and the curtailment of non-synchronous generation, as well as to explore methods to reduce generation cost. Fault ride-through capability, synchronous inertia and fault clearing times are identified as useful tools to reduce the curtailment of non-synchronous generation, especially during periods of low load and high availability of renewable energy sources.

We present a novel technique for determining the solution of optimal power flow, including dynamic security constraints, using forward sensitivities computed by using finite differences. Finite differencing provides an easy way of computing the sensitivities of the dynamic security constraints in optimal power flow. A dynamic security measure based on the frequency excursion of the generators is presented. Our formulation also yields the marginal cost associated with the generator's frequency excursion.

“…During the past decade, TSC-OPF techniques have received increasing attention, with clearly differentiated approaches for representing and assessing the problem of transient stability [1,4]. In the traditional TSC-OPF methods, transient stability constraints are formulated as rotor angle swing equations [1,[5][6][7][8][9][10][11][12][13]. The differential equations used in the dynamic models of synchronous machines are converted to algebraic form, using implicit numerical integration methods, such as the trapezoidal rule and are included in the optimisation model [5].…”
