Abstract
Demand-side management (DSM) represents a potential way to improve the profitability of renewable energy systems. In thispaper, power management including a new DSM strategy in a stand-alone hybrid Photovoltaic (PV)/ Diesel/ Battery system with multiplecustomers has been studied. A new probabilistic model of the consumer behavior based on Bayesian network and Monte Carlo simulation hasbeen carried out so as to capture the real-time and stochastic aspect of the demand. The analysis has been made by means of a one-year periodsimulation of the whole system. Statistical data on consumers and meteorological observation data have been used to set the simulation’sparameters. Numerical results showed that with the implementation of DSM, energy costs are reduced by 11.3% for equal total consumption, andthe use of solar energy resources rose to 54%. This provides insight on the significant performance enhancement offered by a DSM scheme insuch a system.
