The invention discloses a hybrid energy storage optimal configuration method, a medium and a system for a power system. The method comprises the following steps: generating different fault states of an IEEE node system in each scene by adopting an enumeration method; calculating a value of a risk allocation part of each fault element of each fault state of the IEEE node system in each scene; based on the value of the risk allocation part of each fault element of each fault state of the IEEE node system in each scene, weak elements in each scene are identified, and a corresponding severe fault scene of the IEEE node system is obtained; based on a severe fault scene of the IEEE node system, establishing a hybrid energy storage optimization model and constraint conditions of the IEEE node system; and under the constraint of the constraint condition, solving the hybrid energy storage optimization model to obtain rated capacity, rated power and charging and discharging power of a storage battery and a super capaci
