Renewable Energy Technologies: Simulation and Economic Evaluation presents currently available renewable energy technologies (RETs), as well as their possible integration into the economically viable and green residential microgrids of tomorrow. The emphasis is on the importance of RETs in today's energy efficient building design, followed by the RET mathematical models suitable for both performance simulation and economic appraisal. A range of energy storage alternatives, as well as typical energy consumption patterns, are also thoroughly described and precisely simulated. After selecting the right components for a hybrid system, readers are introduced to problems of system integration and optimization, via simulations that enable alternative scenario exercises and comparative analysis. The multicriteria comparison also includes detailed investment appraisal, using both conventional methodology and the authors' novel green-accounting-based appraisal to investigate the impacts on the economic efficiency of the project.
