This effort completed the development of a comprehensive computer program for solar energy storage system simulation models. An acronym for this program 1s SIMWEST (Simulation Model for Wind Energy Storage) and was initially developed under a previous contract, NAS3-20385, August, 1977. The expanded SIMWEST program includes wind and/or photovoltaic systems utilizing any combination of five types of storage (pumped hydro, battery, thermal, flywheel and pneumatic). This expanded SIMWEST software package is available for the UNIVAC 1100 series and the CDC 6000 series computers. The level of detail of SIMWEST 1s consistent with a role of evaluating the economic feasibility as well as the general performance of wind and/or photovoltaic energy systems.nThe SIMWEST software package consists of two basic programs and a library of system, environmental, and load components. The first program is a precompiler which generates computer models (in Fortran) of complex wind and/or photovoltaic source/storage/app1ication systems, from user specifi-cations using the respective library components. The second program provides the techno-economic system analysis with the respective 1/0, the integration of system dynamics, and the iteration for conveyance of variables.
