ABSTRACT: The
risks and challenges faced by human society at the moment are global warming,
climate change and pollution. In addition to their effect on the atmosphere,
the quantity of fossil fuels is beginning to decrease, and countries have taken
steps to encourage greater use of renewable energy resources. This article
explores the feasibility of supplying electricity from a hybrid power system
(HPS) comprising wind/photovoltaic (PV) and batteries. Taking into account
residential buildings that consume the largest portion of energy in Saudi grid, Saudi
Arabia, Riyadh is the preferred city with distinctive geographical and climatic
conditions. The hourly electricity demand data must be over 8760 hours during a
1-year analysis in order to assess the optimum design and operational planning
of the HPS. The economic analysis is carried out by applying HOMER software on
the basis of net present cost (NPC), energy cost (COE) and the renewable
fraction for all situations. In addition, to specify the effect of fuel costs
on the scheme, sensitivity tests are carried out by considering two separate
tariff rates for residential consumers. The results of the economic analysis
show that current tariff is not economic to use
HSP under warm and temperate climate conditions compare to using electricity
from grid and the expected forecasted tariff shows it’s economic to use HSP
compare to grid electricity.
