초록
In line with the government’s policy to expand renewable energy and vitalize the energy new business, the importance of expanding the private sector’s supply of solar energy for housing is also growing. This paper provides basic data in terms of securing economic benefits to lead to the activation of the policy in designing all the rules of the energy prosumer policy. First, the standard housing model was selected and the energy simulation tool was used to derive the annual energy demand and the generation of 5 kW solar power. The economy was then analyzed according to the type of energy prosumer transaction. Three types of models were derived: current energy offset transaction model, optimal selling model through the transaction platform, and best-selling model of surplus power. Among these, the return on the best-selling model of surplus power was found to be the most advantageous. The types of transactions presented in this study will be flexible as the energy market changes in the future, but will be useful in an advance study in designing the rules for rapid institutionalization of energy prosumers.
