Improved load shifting and valley filling strategies in demand side management in a nano scale off-grid wind-PV system in remote areas

摘要

It is reported that residential buildings almost consumed around 30% of electricity generated among other sectors such as industry, commercial and public services etc. In developing countries considerable amount of people have no direct access to the national power grid or are encountered long power blackout. Therefore people in those countries are very limited to use of electricity for routine basic daily applications in their homes. In this study, power demand for those who live in such countries are met by a nano scale autonomous wind-PV system through the demand side management in order to reduce total daily energy cost to reasonable price as much as possible. The preliminary results indicated daily energy cost can be achieved to have competitive prices depending on renewable energy potential and sustainable energy production for 20-25 years of lifetime is also possible for emergency cases.
