Outline of Annual Research Achievements |
At present, on one of the most concerning current issue that is Duck Curve problem. The installations of photovoltaics (PVs) in the smart grid have been growing dramatically because the price of PVs is falling drastically. The massive penetration of PVs' power at the day-time changes the load demand of thermal generations of a smart grid which creates duck shape load curve called duck curve. This research solves the duck curve problem, increase the renewable generation, reduces CO2 emissions and usages of fossil fuels. This research introduces concentrated solar power (CSP) instead of battery storage. This research also considers the consumer sides, they have smart houses. The part of the unique research publishes in IEEE access journal (impact factor: 3.244), recently.

Current Status of Research Progress
1: Research has progressed more than it was originally planned.
Reason
The purposes of this in the field of smart grid systems are to improve the reliability, to improve the stability, to improve the efficiency, to reduce the uncertainty of renewable generations, and improve efficiency of thermal generations, reduce the usages of fossil fuels based thermal generation and increase the share of renewable, decrease CO2 emissions and reduce costs for future smart grid. This research considers consumer side because in future consumers will play a significant role in the world's newest thrust toward lightening the world's dependence on carbon-based fuels and, at the same time, they will save themselves a considerable amount on energy bill for living in smart houses. In this way, we can able to control our energy price and make a zero consumption smart house.

Strategy for Future Research Activity |
Usually, the Concentrated Solar Power (CSP) has stream generator that needs start-up time at least 15 minutes. The quite new proposal for hybrid CSP storage system that will be uninterruptable, any time it can be started and stopped. The design of power system will be done by considering power electronics MATLAB Simulink at first, and implementations will be considering optimization in different challenges in power system. Finally, I will make an experiment of the project by making simple demo CSP power plant. Control system algorithm and constraints will be set-upped in Raspberry Pi for the experiment. This research will reduce the uncertainty of renewables through optimization technique with a hybrid storage system. It helps to reduce CO2 emissions and increases renewable energies.
