Abstract |
: |
The combination of photovoltaic (PV) power supplies, and/or potentially other renewable energy sources, with a diesel generator (D-G) in a hybrid electric power system configuration permits solution to many remote sites power problems. But, the sizing of such systems depending on a short-term data, give not an exact estimation or an appropriate size for the system components, where the number of sunless days is assumed by the designer to assure a reliable power supply. The main problem for long-term systems dynamic sizing and simulation is the site meteorological data base (MOB). In this paper, the MOB module for different sites in Egypt, as example, is created by using the modern renewable energy systems simulation program, INSEL.500, at horizontal and tilted PV arrays plane. The global, direct and diffuse insulation curves during one complete year in El-Giza city, Egypt (site of application) are created and the sort of available solar energy are estimated also.
A computer program for systems dynamic sizing and simulation is developed in FORTRAN language to be compatible with INSEL output data format. In this program, the load profile is divided into two load types, dynamic loads and shallow loads to optimize the operating of difference system components, D-G and PV subsystem, The D-G rating is estimated in the 3kW power-range to handle the load peaks and dynamic loads, and the PV battery subsystem is designed to handle the shallow loads. This program is applied on a case study for an isolated farm, 300km from EI¬Giza city, Egypt. The minimum and hence economical optimum size of storage battery and PV array area of a different degrees of reliability is determined. The loss of load probability (LOLP) and unserved energy (UE) is evaluated and the number of D-G operating hours Is determined at different degree of reliability from 90% to 100%.
The system total life cycle cost (TLCC), the cost for kWp and the cost for kWh are determined and fitted for different degree of reliability. The MOB module and sizing program has the ability to be applied for any hybrid system with load peaks anywhere. |
