Aiming at the choices and risk management that electricity purchasers will face to purchase power in four markets under the framework of the electricity market. This paper, which uses semi-variance to measure risk, has established two risk decision-making models based on restrictive and non-restrictive buy/sell through risks measured by semi-variance. Meanwhile, it proposes to minimize the risks on the basis of historic data and practical statistical genetic algorithms under the premise of benefit guarantee.
