Background: Most non-developing and under developing countries strive hard to tackle
the situation of power crisis and to combat the imbalance between the power generation and load
demand, especially in the case of increasing of the population. In this situation, the load shedding
scheme has been extremely implemented as a fast solution for unbalance conditions. Thus, load
shedding is crucial to investigate supply-demand balancing in order to protect the network from collapsing
and to sustain stability as possible; however its implementation is mostly undesirable.
Objective: prioritize the loads according to their importance and apply reduction strategy in the demands
while the supplied power to the important loads such as health care and security installation
are kept intact without any interruption as possible.
Methods: The conventional methods of load shedding lead to over or under shedding and this may
lead to many problems with the network. Under the scheme, these methods disconnect the load or
the entire feeder without considering their priorities and may not perform as anticipated. In this
work, we propose a logarithmic reduction method to reduce the load according to the priority and
day life criticality. The method for shedding the load base on Reduction Matrix and which in turn
depend on the priority demands.
Results: The higher priority demands are fed with a reliable power source by the real time monitoring
of the network accompanied with power reducing for the lower priority demands.
Conclusion: We test a real data sample provided by the Iraqi national grid control center in Baghdad.
Our simulation results prove effectiveness and practicality of the applied method paving the
way for possible applications in power systems.
