| Abstract | According to seismologists Chile has yet to face another big earthquake in the verynear future, yet the country remains largely unprepared against massive electric powersystems brake-down. The problem lies in the centralized electric power systems andthe lack of adequate technologies and back-up/emergency power systems for disas-ter recovery. The flaws that are built into the very fabric of the presently centralizedpower systems were on full display in the February 27th earthquake in Chile. Nowhereit becomes more evident that hugely centralized power generation and distributionsystems are extremely vulnerable and ineffective to disruptions from natural disasters,human error or other calamities. The large power networks that once proved veryefficient and secure, are now at the center of discussion fueling the need for decentral-ization and the rapid growth of distributed generation (DG). Highly decentralized,diversified and DG-oriented energy matrix is notoriously much better suited to with-stand these disasters. In centralized electric power grids, servicing large metropolitanareas, albeit with some but limited differentiation in service, can only be on or off,so either everyone gets power or no one does. This makes recovering power service inan emergency situation a much more difficult task. On the other hand, decentralizedpower systems (DPS) reduce the obstacles to disaster preparation and recovery byallowing the focus to shift first to critical infrastructure and then to flow outward toless integrated outlets. A DG-based model for a smart micro-grid based on hybridelectric power systems (HEPS) using both renewable energy technologies (RET) andconventional power generation units is presented. The hybrid energy system may beportable or fixed in one place, highly reliable, easy to assemble, modular, flexible andcost-effective solution, that is ready-to-run and go to where it is needed to supplypower in natural disaster. |
