Abstract For the uncertainty of wind turbine, photovoltaic and the load in micro-grid operation, the economic operation model based on chance constrained programming is proposed, with a certain confidence level to meet the backup as probabilistic constraint of reliability. Sequence operation is applied to turn all random variables into one probabilistic sequence, through addition-type-convolution (ATC) and subtraction-type-convolution (STC), so that the probability satisfying the constraints can be calculated directly. The representation is visual and calculating time saving, avoiding the inconsistent results of each calculation using the common analog methods. To reduce the operating costs of micro-grid, the charge-discharge cost is introduced as the energy storage judging indicator to suggest whether charging is profit, so that guide the energy storage system charging during low price period and discharging during the peak price period. The Genetic algorithm combined with sequence operation is applied to optimize the active power and reactive power of micro-source, and to determine the interactive power of interconnection line, thus the best operation mode is formed.
