An intrusive spectral method of probabilistic load flow (PLF) is proposed in the paper, which can handle the uncertainties arising from renewable energy integration. Generalized polynomial chaos (gPC) expansions of dependent random variables are utilized to build a spectral stochastic representation of PLF model. Instead of solving the coupled PLF model(More)
Small isolated power systems are generally located in remote areas which are rather far away from the power grid. Renewable energy such as wind power is introduced into small isolated power systems directly to reduce power generation cost and increase the economy. However, it brings challenges on the operation and control of small isolated power system. To(More)
The application of Battery-based Energy Storage System (BESS) has many benefits in the power grid such as frequency support, emergency assistance, lowering costs, and flattening the load curve. In this paper, a modified stochastic security-constrained unit commitment (SCUC) model is introduced to simulate the daily operation of power system. By setting both(More)
