On grid micro inverter Bolivia

Is a microgrid a good choice for rural electrification in Bolivia?

Historical operation data from the first isolated microgrid for rural electrification in Bolivia (“El Espino”) is analyzed. An un-optimal micro-grid design and un-flexible control strategy have led the system to curtail a 29.7% of the total solar energy available.

Are rural microgrids a problem?

An un-optimal micro-grid design and un-flexible control strategy have led the system to curtail a 29.7% of the total solar energy available. Furthermore, the surveys to the experts on rural electrification show a high degree of uncertainty when forecast the energy demand on rural microgrids.

Can remote PV-diesel microgrids be used for rural electrification?

The historical monitoring data from a remote PV-diesel microgrid in Bolivia for rural electrification is presented. A novel two-stage optimization framework is developed for the robust design of such systems under uncertainty. Components models and performance curves are derived from the monitoring data.

How does a microgrid work?

System description The microgrid has a PV array connected to an inverter, a battery bank connected to a bi-directional inverter and a diesel generator. The nominal capacities are detailed in Table 1 and the layout of the system is shown in Fig. 4.

How are microgrids modeled?

In fact, microgrids components are often modeled in a simplified manner using constant efficiencies or neglecting technological constraints, either due to a lack of data or to reduce the computational tractability, thus increasing what is commonly referred to as “structural uncertainty” [ 9 ].
