The paper concerns the estimation of state a power system in which there is phase shifter called quadrature booster. aim comparative analysis two different cases including booster estimation. In first case, represented by model consisting real voltage sources, one series with line and other shunt branch. second model, branch as off at end where considered actually installed. assumed to be carri...

Power system state estimation (PSSE) is commonly formulated as weighted least-square (WLS) algorithm and solved using iterative methods such Gauss-Newton methods. However, have become more sensitive to operating conditions than ever before due the deployment of intermittent renewable energy sources, zero emission technologies (e.g., electric vehicles), demand response programs. Appropriate PSSE...

Power system dynamic state estimation (DSE) remains an active research area. This is driven by the absence of accurate models, increasing availability fast-sampled, time-synchronized measurements, and advances in capability, scalability, affordability computing communications. paper discusses advantages DSE as compared to static estimation, implementation differences between two, including meas...

<span>In this study, a novel technique is used to estimate the power system harmonic state, as one of biggest risks in network. Nonlinear loads are widely used, which inject harmonics into system. Such injected make networks unstable and increase loss. The main objective work develop new state estimator accuracy, stability wall operation state. Three computational methods that is, i) prop...

With the development of modern society, the scale of the power system is rapidly increased accordingly, and the framework and mode of running of power systems are trending towards more complexity. It is nowadays much more important for the dispatchers to know exactly the state parameters of the power network through state estimation. This paper proposes a robust power system WLS state estimatio...

In the restructured environment of electricity market, firstly the generating companies and the customers are looking for maximizing their profit and secondly independent system operator is looking for the stability of the power network and maximizing social welfare. In this paper, a one way auction in the electricity market for the generator companies is considered in both perfect and imperfec...
