Abstract To respond to the situation that the deterministic energy-saving assessment can not fully meet the requirements of energy-saving management in stochastic environment, a novel stochastic programming power purchasing model of power grid corporation considering energy-saving benefit risk assessment in energy-saving electricity markets is presented in this paper. Firstly, considering transmission loss and coal consumption in trading,an energy-saving benefit assessment index of unit electric quantity is presented in energy-saving electricity markets; followed by an power purchasing energy-saving benefit risk index of power grid corporation which imports the concept of semi-absolute deviation risk in economics portfolio theory and considers the stochastic behavior of electricity price, hydroelectricity production and load demand in energy-saving electricity markets. Then, a power purchasing model of power grid corporation considering energy-saving benefit risk assessment is built in the framework of stochastic programming theory so as to meet energy-saving benefit risk optimal management in energy-saving electricity markets. The model is solved by a genetic algorithm embedded with Monte-Carlo simulation technique and objective relative dominant strategy. Finally, the simulation results of a real provincial power grid show the effectiveness of the proposed energy-saving benefit risk assessment index and power purchasing model.

Key words： Electricity market energy-saving risk assessment index power purchasing model genetic algorithm
