Modern power systems must deal with a greater degree of uncertainty in flow calculation due to variations load and generation introduced by new technologies. This scenario poses challenges system operators which require tools for an accurate assessment the state. paper presents interval (ILF) approach dealing analysis. A probabilistic (PLF), based on Monte Carlo Simulation (MCS), was also imple...

Congestion management in electricity markets is traditionally done using deterministic values of power system parameters considering a fixed network configuration. In this paper, a stochastic programming framework is proposed for congestion management considering the power system uncertainties. The uncertainty sources that are modeled in the proposed stochastic framework consist of contingencie...

This paper proposes a stochastic framework for demand response (DR) aggregator to procure DR from customers and sell it to purchasers in the wholesale electricity market. The aggregator assigns fixed DR contracts with customers based on three different load reduction strategies. In the presented problem the uncertainty of market price is considered and the risk of aggregator participation is ma...

Systematic consideration of uncertainty in data, model structure, and other factors is generally unaddressed in most Total Maximum Daily Load (TMDL) calculations. Our previous studies developed the Management Objectives Constrained Analysis of Uncertainty (MOCAU) approach as an uncertainty analysis technique specifically for watershed water quality models, based on a synthetic case. In this stu...

This paper proposes a scheduling method of dual ESSs (Energy Storage Systems) for the purpose reducing peak load when there are sudden loads or generation changes during on-peak time. The first ESS is scheduled once day based on day-ahead prediction, and second every 15 min time short-term prediction by LSTM (Long Short-Term Memory). Special attention paid to training using augmented past data ...

Present development and production of power transformers with lower losses in addition to replacement of outdated transformers assume regular measurement of losses in both load and no-load regime. These measurements are very demanding especially in the case of on-situ measurements. The complexity of the measurements grows with the size of transformer. This paper presents one typical test of los...
