ABSTRACT
Chapter 11 discusses microgrid islanding. There are remote locations where the only way to provide electrical power is to establish local energy systems. What are the characteristics of island microgrids and what makes them successful? Local island microgrid solutions can be competitive in cases where the synchronous network is available, but new approaches are needed for economic reasons. One catalyst for this new approach to microgrid deployment is the growing renewable generation industry. This chapter provides an in-depth island microgrid case study which considers the possibilities of local energy supply systems. In this chapter, service quality is analyzed, construction and operational requirements are cited, and through on-site measurements, a renewable energy mix optimizer application is introduced. Based on the measurements and operational experience, a calculation methodology is established to compare the traditional supply solutions with islanding operations. Using the comparison of network development costs and islanding solution costs, an optimal weight factor can be defined, which can be an effective investment decision support parameter.
