Recently the power system state estimator was shown to be vulnerable to malicious deception attacks on the measurements, resulting in biased estimates. In this work we analyze the behavior of the Optimal Power Flow (OPF) algorithm in the presence of such maliciously biased estimates and the resulting consequences to the system operator. In particular, we characterize the set of attacks that may lead...
With the increasing levels of wind generator penetration in modern power systems, one of major challenges in the present and coming years is the optimization control, such as optimal power flow including wind farms. The power flow model for a fixed speed wind generator (FSWG) system and a variable speed wind generator (VSWG) system is discussed respectively. The expectation model of wind generators'...
This paper generalizes Benders decomposition to maximize a nonconcave objective function and uses that decomposition to solve an ldquoelectric power grid interdiction problem.rdquo Under one empirically verified assumption, the solution to this bilevel optimization problem identifies a set of components, limited by cardinality or ldquointerdiction resource,rdquo whose destruction maximizes economic...
The desire to reduce harmful emissions from electricity production has led to an increase in the connection of renewable energy generation. Active network management (ANM) is one proposed method for allowing additional network connections without reinforcement of electricity networks. This paper presents a case study exploring the initial layers of a modelling and simulation framework for active networks...
Power system security requires the modeling and simulation of catastrophic contingencies that could be present in the system collapse or blackouts. Thus, power system operators require analysis tools that give them information in order to take preventive and corrective actions to operate the system in a reliable way. Generally, this type of analysis involves simple componentpsilas contingencies based...
