분산형전원 사업자와 소비자 간 전력거래에서 전력도매가격과 계시별 요금제를 고려한 사회후생 최대화 전략에 대한 연구

Abstract

Aggregators of distributed energy resources and consumers in the distributed energy system can transact electricity with various ways. The aggregators and the consumers can contract the appropriate power generation or power demand due to advances in the power communication. Although the aggregators and the consumers would not contract others in the conventional power system, the necessity of transaction between them will increase in the decentralized power system. The adequate operation strategies for aggregators and consumers are required to enhance their contracts and increase their benefit. In this study, we propose an operation strategy for distributed energy resources aggregators and consumers in order to maximize the social welfare. The proposed model considers the transaction between the aggregator and the consumer. The results demonstrate that the maximum social welfare can be achieved by considering the transaction between the aggregator and the consumer.
