This paper systematically discusses two-population asymmetric evolutionary games (2PAEGs) from the perspective of decision-making behavior characteristics, and applies these game models to a two-population supply-side electric power bidding market. First, a 2PAEG model is established. Then, complete evolutionary equilibrium rules of this model are revealed during decision-making processes. Discussion shows that final evolutionary game equilibria achieved in the 2PAEG model are only determined by some payoff parameters, which are defined as relative net payoff (RNP) parameters in this paper. Finally, a case study of supply-side bidding simulation for two generator populations is conducted, which can effectively verify the universality and effectiveness of the evolutionary dynamics results obtained in the established general 2PAEG model. Moreover, it shows that reasonable policies made by the government can guide more appropriate power bidding for onto-grid electricity.

Reliability of both power and gas supply is affected by the interdependence between two systems because the coupling between electricity and gas network becomes closer nowadays. It is urgent to research on reliability assessment in electricity-gas coupled energy system, and the reliability of power supply in electricity-gas coupled system is study in this paper. Reliability models of coupled devices are established. Besides, the algorithm and program based on analytical method which has more practical value of engineering are designed. Finally, the Belgian 20-bus gas network and IEEE -33 system are used for a case study. Effectiveness of models and method is verified and tested.

A reliability evaluation method for the electricity- gas coupled system considering correlation is proposed. Firstly, the point estimate method is applied to the system reliability evaluation process. Since correlated variables could not be used in the point estimate method directly, Nataf transformation is adopted to deal with the correlation. Then, a novel general method to solve the transformed correlation coefficient matrix in Nataf transformation efficiently is researched. Finally, an electricity-gas coupled system consisting of a modified IEEE-RBTS Bus6 NO.4 feeder system and a modified NGSIO node natural gas system is constructed, and results indicate effectiveness and high efficiency of the proposed method.
