Abstract: Aiming at solving the economic operation problem when large scale of distributed energy resources (such as photovoltaic, wind power and energy storage) integrated into distribution network and to improve the real time ability, robustness and flexible scalability of the control strategy, a distributed consensus based collaborative control strategy was proposed. The power sources were controlled in a distributed way. The optimal operation point was realized in the condition that each power source could only collect information from its own and its neighbors. The results indicate that the proposed strategy is effect in real time economic dispatch in cases of peak valley price, intermittency of the renewable energy and power fluctuation of the load.

Key words: economic dispatch; collaborative control; consensus based algorithm
