“…Integer variables were not considered as each sub-problem was solved using an interiorpoint method. The use of the predictor-corrector interior-point method for preventive/corrective control of the network under one operating condition was discussed earlier in [12]. More recent research has shown that problems similar to reactive power planning can make use of sensitivity information in sequential MILP procedures that handle discrete variables [13].…”

This paper presents a new method for VAr planning under multiple operating scenarios, optimizing sizes and locations of new reactive compensation equipment to ensure that both the system voltage profile and voltage stability requirements are met. The approach is based on 1 -norm regularization for finding a solution with minimum VAr installation sites and on the 2 -norm penalty function for satisfying the multiple state constraints. The 2 -norm penalty function is exact in the sense that a finite penalty parameter is required to establish equivalence with the VAr planning problem, thus avoiding numerical ill-conditioning. The solution is obtained from a successive conic programming algorithm which makes use of adaptive trust-region control. The results of the new method are compared with those of an optimal power flow-based program for VAr planning.Index Terms-Nonlinear programming, optimal power flow, optimization methods, reactive power control.

“…The dynamics associated with voltage stability are often slow, and hence static approaches may represent a good approximation. The basic idea behind this approach is to identify a feasible solution to the power-flow equations [7][8][9][10].…”

“…In most of these [7][8][9], the voltage stability is modeled indirectly by maintaining voltage and transfer limits that are calculated off-line. This is not always true for power systems, as has been well debated in the literature [11,12].…”

“…Fault happens occasionally in such power system, which results into serious blackouts. When the power system operates at insecurity or the stability domain of the operating point is not enough, preventive and corrective controls will be adopted [1]. When it does not work for the power system stability enhancement after the control of generator, switching capacitor or the OLTC triggered, the emergency control of load shedding will be used as the last measurement to prevent the power system blackouts [2].…”

With the method of modal analysis, the full Jacobian according to the power system power flow equations is studied and a method to identify the suitable bus for loading shedding is proposed in this paper. The proposed method makes use of the participation factors corresponding to the active power, by which the structural characteristic of the power system nonlinearity is included. As a result, the effective bus where the load shedding should be used can be found. In order to show the effectiveness of the proposed method, the WSCC 9-bus power system is used as an example. The simulation results indicate that with the load shedding at the place where the proposed method decided, the voltage stability indices are considerably increased. The proposed method in this paper is effective.
