Abstract

The load shedding scheme has been extensively implemented as a fast solution for unbalance conditions. Therefore, it's 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. One of the solutions to minimize the amount of load shedding is the integration renewable energy resources, such as wind power, in the electric power generation could contribute significantly to minimizing power cuts as it is ability to positively improving the stability of the electric grid. In this paper propose a method for shedding the load base on the priority demands with incorporating the wind power generated. The higher priority demands are fed with a reliable wind energy resource in order to protect them from shedding under contingency condition such as high overloading by the real time monitoring of the network accompanied with power reducing for the lower priority demands. The simulation results prove effectiveness and practicality of the applied method paving the way for possible applications in power systems.

Highlights

  • Most non-developing and under developing countries strive hard to tackle the situation of power crisis and to combat the imbalance between supply-demand power, especially in the case of increasing of the population which lead to the load exceeds the limitation of the network

  • One of the solutions to minimize the amount of load shedding is the integration renewable energy resources, such as wind power (WP), into the electric power generation could contribute significantly to minimizing power cuts as it is the ability to positively improving the stability of the electric grid

  • The higher priority demands (PDs) are fed with a reliable power source with the penetration of wind generation by the real-time monitoring of the network accompanied with power reducing for the lower PDs

Summary

Introduction

Most non-developing and under developing countries strive hard to tackle the situation of power crisis and to combat the imbalance between supply-demand power, especially in the case of increasing of the population which lead to the load exceeds the limitation of the network. The LS based on importance has been proposed for loads to progress the execution of the power system during contingencies and to minimize the impact of the LS on the consumers by taking the social factors into consideration ,Rao, et al, 2013; Laghari, et al, 2015; Esttaifan and Al-haddad, 2017 These LS schemes do not consider the effects of the high penetration and the contribution of each wind generator on the LS performance of the system in their research. We propose a LS strategy based on priority demands (PDs) considering the WP generation Through this approach, we first prioritize the loads according to their importance into account the penetration of the WP.
