Science and Education Publishing American Journal of Electrical and Electronic Engineering 2328-7357 1 1 2013 02 26 Price Based Unit Commitment Considering Fuzzy Uncertainty 10 14 EN Reza Khorramnia Department of Electrical Engineering, Safashahr Branch, Islamic Azad University, Safashahr, Iran Soroush Karimi Khorrami AJEEE2013112 10.12691/ajeee-1-1-2 2012 12 30 2013 01 26 2013 02 26 In deregulated systems, bidding plays an important role for Gencos participating with the objective of maximizing pro?t. While making bidding strategies, factors like unit constraint and price uncertainty need to be considered as they have direct impact on the expected pro?t. The goal of the partnership units of solution is based on the price. By solving this problem, the generation company to determine the optimal generation schedule and unit status hourly. MCP plays an important role in the profitability of the units. In this paper, a novel approach to solving an optimal bid curve underprice uncertainty using PBUC in PAB markets is presented. Numerical results show the suitability of the method on a sample market.
