Recently, as one of policies for carbon dioxide reduction, operation method of independent power system replacing diesel generator with renewable energy such as wind power and photovoltaic (PV) system has been presented. Therefore, this paper proposes an operation algorithm and modeling of independent power system by considering CVCF (constant voltage constant frequency) ESS (energy storage system) for constant frequency and voltage, LC (load control) ESS (energy storage system) for demand and supply balancing and SVC (static var compensator) for reactive power compensation. From the simulation results based on the various operation scenario, it is confirmed that proposed operation algorithm and carbon dioxide reduction in independent power system.

This paper deals with a evaluation simulator and technical problems for the protection devices, composed of distribution system simulator, PV systems simulator, monitoring and control systems with the LabVIEW software. The simulator can analyze the customer voltage characteristics of normal conditions using the LabVIEW software. This paper presents the concept for voltage drop calculation algorithm and customer voltage variation. The simulator can provide the analysis of the power quality of the power quality problems in distribution system by considering the three parameters such as photovoltaic (PV) systems capacity, system configuration and load factor.
