Optimal Dispatching of Wind-photovoltaic-thermal-storage Combined System Considering Minimum Inertia Constraints
摘要
Abstract
The integration of new energies such as wind,photovoltaic and storage power makes the system often operatein low inertia scenarios,posing significant challenges to the optimal dispatching of system while ensuring the frequency stability. In this paper,an optimal dispatching model of multi-source combined power system considering minimum in-ertia constraints is proposed. First,by taking into account two frequency indexes,the minimum inertia that is needed to meet these indexes is calculated,and the nonlinear frequency stability constraint is transformed into a linear minimum inertia constraint,which is further added to the dispatching model. Second,the fuzzy parameter-based chance con-straints are incorporated to indicate the effect of source-load uncertainties on the combined system,and the optimal dis-patching model of system under fuzzy parameters is established. Finally,the economy and safety of the proposed model is validated using an IEEE 30-node system.关键词
