A variety of technology options were studied by NASA during the pre-RFP period of the program. It was concluded that both photovoltaic and solar dynamic power conversion systems should be evaluated in depth. Within each of these general approaches are further choices which must be studied. For photovoltaic systems they include cell size, array structure, assembly method, and electrochemical energy storage technique. Solar dynamic systems (Rankine, Brayton, Stirling) require different onsiderations in the design of the solar concentrator and the heat receiver/storage unit due to variations in the operating conditions and working fluids used. Assembly methods are also an important design consideration. This paper reviews the requirements to be met by the Power System, characteristics of the major technology options being considered, and the approach to be taken in the definition studies the role of advanced development in the definition process and the specific tasks to be performed under the Phase B contracts. NASA Lewis' approach to managing the complex power system interfaces across the station is also discussed.
