Analysis and Design Micropower Energy Systems

It is known that the design of each power system is a complex task. This fact holds true for micro-power systems too. Design solution should provide the answers to some complex issues related to the need to include certain components, their cost, efficiency, size and configuration of the system that can be used. It is known that when designing a system, in this case the energy system, it is necessary to provide input model parameters, which describe the technological options, costs of components, and the availability of energy resources. By using HOMER software package, it is possible to simulate different system configurations that can be further sorted by cost. This method enables comparison of configuration and to evaluate them in relation to the economic and technical value of the energy system configuration. In addition, it is possible to calculate the balance of energy for each system configuration, which is to be considered, and then decide whether the configuration is feasible, then estimate costs of installing and operating the system during the project period. Also we can calculate the cost of the system, such as capital costs, replacement costs, operation and maintenance, fuel and interest. In this paper a diesel micro-power system will be presented. Analyses will be conducted interrogation that should answer whether it makes sense to add wind turbines and capacitor banks in the existing system in the event of certain circumstances. Design and analysis will be performed using HOMER software package.
