Under voltage load shedding (UVLS) and under frequency load shedding (UFLS) is plays vital role in the power system operation. As large disturbances are occur frequently in previous days. Generally these two methods are work independently from each other, and are not designed to integrated way to use their combined effect on load shedding. The reactive power hardly consider in load shedding pro...

After occurrence of some disturbances in power system that causes the sever imbalance between generation power and electrical load, the power system frequency begins to decrease. To prevent power system frequency instability and stop the frequency decay below the power system allowable frequency limitation, load shedding schemes should be utilized by applying under frequency load shedding relay...

This paper targets the unexplored problem of demand response within the context of power-grids that are allowed to regularly enforce blackouts as a mean to balance supply with demand: highly-stressed grids. Currently these utilities use as a cyclic and binary (power/no-power) schedule over consumer groups leading to significant wastage of capacity and long hours of no-power. We present here a n...

In recent years, the use of renewable energy sources in micro-grids has become an effective means of power decentralization especially in remote areas where the extension of the main power grid is an impediment. Despite the huge deposit of natural resources in Africa, the continent still remains in energy poverty. Majority of the African countries could not meet the electricity demand of their ...

we can improve the performance of distributed systems by load sharing (i.e., distribute load from heavily loaded nodes to lightly loaded ones). Adaptive load sharing policies take system state into account in making job distribution decisions. We can maintain the state information in one of two basic ways: distributed or centralized. This paper discuss on distributed systems which rely on eithe...
