Power distribution method and device for hybrid energy storage system considering active deviation assessment

Abstract

The application provides a hybrid energy storage system power distribution method and device considering active deviation examination, and the method comprises the following steps: when a new energy station is in a non-examination period of active output deviation, lithium battery energy storage subunits in a hybrid energy storage system of the new energy station perform adaptive energy regulation according to electricity prices, and super capacitor energy storage subunits perform adaptive energy regulation with SOC as 50% as a regulation direction; when being in an active output deviation examination period, an optimization model of hybrid energy storage system power distribution is established and solved to obtain optimization results of lithium battery energy storage subunit output and total output of super capacitor energy storage subunits; then, an optimization model of super capacitor energy storage subunit power distribution is established and solved to obtain optimization results of super capacitor energy storage subunit output. The application can solve the problem that after the new energy station is configured with the hybrid energy storage, different types of energy storage resources are fully utilized to reduce the additional operation cost caused by power deviation examination.
