Distributed generation is attracting much mindfulness as a viable option to giant centralized generation plants, driven by the fast evolving liberalization and deregulation environments. This interest is also motivated by the need for eliminating the needless transmission and distribution costs, drooping the greenhouse gas emissions, deferring capital costs and improving the availability and consistency of electrical network Therefore, disseminated generation is expected to play an escalating vital role in meeting future power generation supplies and to provide consumers with elastic and cost resistive solutions for many of their energy needs. However, the integration of these sources into the electrical network can cause some challenges regarding their expected impact on the safety and the active behavior of the full network. It is vital to study these issue and to analyze the permakeedance of the expected future systems to guarantee satisfactory operation and to maximize the benefits of utilizing the dis- tribute resources.
