WIND & HYBRID SYSTEMS
are now able to match the strengths of very different power sources
in a single advanced generating system. These new hybrid systems
are making tremendous improvements in the field of remote power
supply toward the goals of lower energy costs, utility-grade power
and continuous power availability.
A PV power system can by hybridized with virtually any other power
source, but the most common hybrids are Thermo Electric Generators
(TEG), diesels, and wind generators. When hybridizing PV systems
with engine-driven generators, a common design technique is to size
the PV array to support the load most of the time, with the engine
generator simultaneously supporting the load and charging batteries
when solar energy is limited.
Hybrid systems are typically used where:
- The reliability afforded by the dual power source is vital
- The characteristics of the power sources are complementary.
For instance, a PV-wind hybrid might be appropriate at a site
with poor winter solar insolation but strong winter winds.
- The hybrid generator configuration is more cost effective than
any single power technology.
- When available load is used, ther generator can supply the additional
load requirement.
