Optimal coordinated scheduling of combined heat and power fuel cell, wind, and photovoltaic units in micro grids considering uncertainties

<p>This article describes the performance results of the first renewable microgrid of Chocó, Colombia, monitored over two years (2016-2017) adding an economic approach. A virtual platform is used to analyze, in real time, the microgrid power production, while a meteorological station measures the solar irradiance and the ambient temperature. The results indicated that the generation of AC PV energy was 21,817 kWh/year on 2016 and 23,301 kWh/year on 2017. The photovoltaic system’s average efficiency was 10.3 % on 2016 and 11.09 % on 2017. An economical analysis of the renewable microgrid is also presented using RETScreenTM software. The results show a net present value of $237,028 USD for an evaluation period of 25 years with annual energy savings of $4,622 USD. A calculation on greenhouse gas emissions show that 22.9 tCO2 per year are avoided when using the solar energy tech.</p>

“…In another study, an analysis and simulation was presented for the building-integrated photovoltaic thermal (BIPVT) configuration with respect to changes in the weather conditions [59]. Also, a model for a combined heat and power photovoltaic, fuel cell and wind turbine micro-grid was provided, considering all variable parameters [60]. This model could enhance the efficiency of the CHP system.…”

A main method to increase the solar energy utilization efficiency is to combine heat and power generation together. In this paper, a critical review of the literature on solar combined heat and power systems (CHP) is conducted, which includes solar photovoltaic/thermal systems, concentrated photovoltaic/thermal systems, and various combination with different solar collectors and applications. It shows that there are serious gaps in this field, which calls for more research. The modeling and analysis of the electrical parts of the CHP systems are not adequate, and there are limited studies on the economic and exergy assessments of the solar concentrating CHP systems. The solar collectors for combined CHP were focused on optimizing the performance of the maximum average useful power generation and minimum total heat transfer area, little environment impact analysis was conducted. Careful exergy, economic and environmental analysis on both electronic and thermal performance is suggested, especially for large CHP system.

A novel micro-solid oxide fuel cell (µ-SOFC), with a rectangular saw-tooth shape, was designed with a 50 wt% BYCF + 50 wt% GDC 10 cathode and a 60 wt% NiO + 40 wt% GDC 10 anode deposited on a GDC 10 electrolyte substrate by the spray pyrolysis technique. µ-SOFC receives methane only (CH 4) as fuel gas from one side. The fuel gas was applied at a flow rate of 0.2 l min −1. The power density obtained was 1.0 µW at 800 • C. Voltage levels generated by the µ-SOFC at 40-99.99% CH 4 was highly accurate representing the quantity of CH 4. Low accuracy was observed at 10-30% of CH 4. Therefore, µ-SOFC is an application of SOFC technology to be a sensor for economically detecting CH 4 in a biogas system, while being capable of operating in humid conditions at high temperatures.
