With the increasing penetration of photovoltaic (PV) power system into the utility network, the issue caused by the fluctuation and intermittence of PV power output draws more attention. In order to predict the hourly power output for a PV system without any complex meteorological instrumentation, a NARX network-based forecasting model is proposed in this(More)
Given several algebraic surfaces and corresponding auxiliary planes, a scheme for constructing a piecewise algebraic surface to blend the given surfaces is presented along the intersection curves of the given surfaces and their corresponding auxiliary planes. The algorithm starts with the suitable partition of the 3D space into tetrahedrons or prisms in(More)
