<p>PROBLEM TO BE SOLVED: To provide an energy prediction method in solar power generation, which predicts energy generation when the generating power is suppressed. SOLUTION: Employment of a characteristic structural method for predicting energy generation: a maximum-possible solar-cell generating power WPVM(t), which is the maximum power a solar cell can generate, and is calculated from intensity of insolation I(t) at arbitrary intervals at the installed place of the solar cell, is compared with an acceptable power Ws (t-Δt), which is derived from the sum of a load-consuming electric power W1 (t) and a chargeable power Wb (t) of an electric storage means, where the conversion efficiencyηof a power conditioner is taken into account; and if a relation of WPVM(t)>Ws (t-Δt) is satisfied, a generating power WPV(t) = Ws (t-Δt) is assumed, and if not satisfied, the generating power WPV(t) = WPVM(t) is assumed.</p> |
