A flexible and computationally effi cient analysis technique for designing and evaluating grid-connected photovoltaic (PV) systems is introduced, which establishes a direct relationship between the inputs to the system, temperatureand irradiance, and system performance criteria. For a given...

The increasing complexity of building energy systems integrated with renewable energy systems requires essentially more intelligent scheduling strategy. The energy systems often have strong non-linear characteristics and have discrete working ranges. The mixed-integer nonlinear programming...

An extended-power pinch analysis (EPoPA) is proposed as a means of extending the power pinch analysis (PoPA) for optimal design of renewable energy systems with battery and hydrogen storage (RES-BH). The EPoPA concept is based on the storage of wasted electricity that cannot be stored by the...

In a zero energy home annual energy consumption is equal to the annual energy production using one or more available renewable energy resources. In St John’s, Newfoundland wind is the readily available renewable energy resource. The average annual wind speed in St John’s is 6.7 m/s. This...

This study presents an analysis of the technical and financial viability of grid-only, RES-only and grid/RES hybrid power supply configurations for a large-scale grid-connected hotel (over 100 beds). Assessment criteria comprised net present cost (NPC), renewable fraction (RF) and payback time....

Based on 25 years of involvement in a number of important and representative political decision-making processes in Denmark and other countries, this paper presents the unified learning of some of the institutional barriers one will meet when radical technological changes such as the replacement...
