This paper proposes a robust interval optimization method to address the challenges associated with wind power integration and enhance the flexibility of a power system. By introducing flexibility resources from a district heating system, the method provides a reliable dispatch plan that can accommodate uncertainties and fluctuations in wind power generation. Case studies demonstrate that the proposed approach effectively enhances the integration of wind power and improves the overall reliability and flexibility of the energy system.
The increasing penetration of renewable energy, particularly wind power, and the integration of different energy systems have become two major trends in the development of energy systems. In this context, this paper proposes a robust interval optimization method for combined heat and power dispatch (CHPD) to address the challenges associated with wind power accommodation. To enhance the flexibility of a power system and support the integration of wind power, flexibility resources from a district heating system are introduced in the economic dispatch. To ensure the safety and reliability of the CHPD results, a robust interval optimization method is employed. By considering a range of possible wind power outputs, the robust interval optimization method provides a robust and reliable dispatch plan that can accommodate uncertainties and fluctuations in wind power generation. To verify the effectiveness of the proposed model and method, case studies were conducted on a 6-bus electrical power system connected with a 6-node district heating system. The results demonstrate that the proposed approach can effectively enhance the integration of wind power and improve the overall reliability and flexibility of the energy system.
