PROJECT TITLE :

Probabilistic Assessment of Available Transfer Capacity via Market Linearization

ABSTRACT:

Uncertainties related to bus loading and elements' availability result in uncertainties in several system variables based on the system physical and economical relationships. Line flows, bus voltages, completely different prices, and different variables and indices, like on the market transfer capability (ATC), are stochastic and cannot be expressed as a determined quantity. Historically, so as to model the stochastic nature of power systems, a stochastic power flow algorithm is employed. During this paper, stochastic-algebraic method is applied to search out the chance density perform (pdf) of ATC. The algorithm linearizes the optimal power flow formulation and uses Gram–Charlier expansion to seek out the pdf of the ATC, based mostly on the statistical moments. The main contribution of this paper is that the market clearing equations are linearized rather than the ability flow equations. Additionally, in most of previous studies, the results of system uncertainties have been neglected in ATC calculations. The other advantage of the proposed methodology is that the program execution time is very short. The proposed technique is tested on the IEEE Reliability Take a look at System, and also the results are compared with those drawn using Monte Carlo simulation to point out the effectiveness of the proposed methodology.
