This paper discusses of all the consequences and effects after loss electrical systems caused by hurricane Maria on island Puerto Rico. Rico is in Caribbean very susceptible to catastrophes due natural events which cause different social population. In this article, major affected areas will be mentioned, from water communications health economy Hurricane Maria. We mention fragility country's infrastructure possible measures re-establish these services most expeditious manner. The disasters...
Multilevel inverters are used in many applications the industry, due to its power quality advantages. In this paper, a multilevel inverter is designed along with photovoltaic array as source three-phase AC load. To regulate voltage of (PV) panel array, dc-dc boost converter added system. The output input that will 3-phase based on five-level signal and topology uses 9 switching devices. This same number levels existing topologies reduced components. proposed less devices than topologies....
This paper presents a voltage control strategy based on the optimal duty cycle for renewable energy system comprised of Thermoelectric Generator (TEG) in cascade with KY-Converter, voltage-boosting topology, and coupled to resistive load. The mathematical model that describes TEG is presented as well derivation values (i.e. current voltage) provide maximum power. equations KY-Converter are described, including averaged terms Duty Cycle using switching transistors topology. different steps...
Natural disasters are increasingly impacting the power availability to communities around world causing long term blackouts. Rural and remote at a greater risk of suffering longer blackouts due being lower priority or more difficult during energy restoration efforts. The impacted by tend be economically disadvantaged remote. Fuel pipelines unavailable fuel delivery is interrupted as resources diverted higher population areas; this makes installation PV plus storage very attractive. This...
Reducing the duration and frequency of blackouts in remote communities poses an engineering challenge for grid operators. Outage effects can also be mitigated locally through microgrids. This paper develops a systematic procedure to account these challenges by creating microgrids prioritizing high value assets within vulnerable communities. Nighttime satellite imagery is used identify Using asset classification rating system, multi-asset clusters are prioritized. Infrastructure data,...
