Power systems, the core of urban critical infrastructures, suffered heavy losses due to earthquakes. With the development of seismic resilience, seismic research of power systems have been extended to the overall concern of seismic performance, restoration and reconstruction. It is necessary to assess the response of power systems under earthquakes. In order to quantify and improve the seismic resilience of urban power systems, we combine physical element, abstract network and external influence, and assess the power system seismic resilience. Four-dimension seismic resilience assessment framework is proposed by comprehensively considering four dimensions (STEP), including social indicators (affected infrastructures and public services), technical indicators (power function calculated by DC power flow analysis), economic indicators (community GDP), and population indicators (affected population). Moreover, we determine static importance of power systems based on four-dimension framework. The research results show that single dimension resilience assessment may underestimate the actual disaster consequences of the power network. The multi-dimensional performance recovery curve is greatly affected by repair order and resource allocation. Four-dimension (STEP) can better reflect the actual situation of power system technology damage and recovery under earthquake. STEP resilience assessment framework integrates the impacts of society, technology, economy and population on the seismic resilience of power system, and has good practical significance and promotion significance.
