Abstract：Aiming at the issues of stable economic operation of energy base as well as efficient consumption of large-scale new energy under the wind-photovoltaic-thermal integrated scheduling mode, this paper proposes a multi-energy complementary optimized scheduling model integrating multi-objective and multi-time scales, which fully considers the optimization focus under different operating conditions of the energy base. With the objectives of maximizing the consumption of new energy, minimizing the cost of peak shaving, and optimizing the economic operation of the system, the branch-and-cut method is used to solve the problem under safety constraint conditions, and the plan is continuously revised based on the day-ahead to intra-day multi-time scale collaborative scheduling framework. A large energy base in Inner Mongolia is selected as an example for case analysis, the result of which, further enhanced the collaborative power generation capacity of wind, photovoltaic, and thermal power, as well as improving the overall economic efficiency of the system operation, promoting the efficient consumption of renewable energy while ensuring the safe and stable operation of the system.
