Optimal economic dispatch for intelligent community micro-grid considering demand response

Using in thermal load dominant mode will restrict the flexible output of the micro-combustion engine for the combined heat and power supply system (CCHP), this paper established a joint model of multi-energy flow micro-grid for intelligent community combined with the time-sharing price response and compression chiller. The mathematical model of the maximum integrated operating income of the system, which is based on the installation of the compression chiller to decouple the system cooling and consider the influence of the time-sharing price on user's electrical habits. And the Shuffled Frog Leaping Algorithm (SFLA) is used to optimize the cooling load model after the user load response. The results show that the SFLA algorithm can obtain the faster global optimal solution and the better fitness value of the model.
