Allows very detailed analysis for energy sources, system architectures, and dispatch strategies
Does not consider short term system fluctuation due to system dynamics or component transients, not suitable for economic and multiobjective optimization
Institute for Energy Technology, (Norwegian University of Science and Technology, Trondheim)
Used to analyze performance of hydrogen energy systems; simulate hydrogen mass flows; and estimate electrical power flow in standalone and hybrid generation system
Australian Business Council for Sustainable Energy (BCSE)
Consumption and power generation give a good general impression of system performance over course of the year
Layout of generator input form is not always optimal in terms of clarity, even after feeding PV irradiation, temperature, generator size, values of shiny and cloudy months, annual mean value, and so forth
Time step simulation program for off-grid and grid coupled solar generation systems; capable of performing energy calculations, analysis of economic efficiency, and analysis of influences of shadowing
Limits available options for energy sources, system architectures, and dispatch strategies
Provides dimensioning proposals for standalone installations (PV and battery size) and warns user if chosen component combinations are not technically feasible
No inverter models for off-grid system simulation; only DC modeling is possible
Other reported tools are Jpelect, PV-DesignPro, PowerSim, Off Grid Pro, Power Factory, Off Grid Sizer, Sunny Island Design, TALCO, INSEL, ARES, RAPSIM, SOMES, SOLSIM, Simplorer, Solar Pro, and HSWSO (Hybrid Solar-Wind System Optimization Sizing).
