different formulations. Likewise, employing the same legends as Figures 6.8 and
6.9 to explain the results, Figure 6.10 describes the different aggregated micro-CHP
generation profiles obtained from running the various simulations.
The following conclusions can be drawn from the micro-CHP operation results:
Although cases 2, 3 and 4 produce approximately the same amount of distributed
generation, their production is not as abundant as cases 5-7. Therefore, the
technology is underutilised due to its operating features described in Table 6.2;
●
Although case 5 focuses on loss reduction, the use of cogeneration facilities is
greater for it than for cases 2, 3 and 4; this is achieved by charging the thermal
storage facilities during moments of low demand and discharging them when
convenient;
●
Cases 6 and 7 have the same results, clearly obtaining the most benefit from CHP
production. The motive is quite simple; these scenarios create an environment
