Currently, with the increasing interest in renewable energy sources (RES), their penetration in the power system is expected to increase considerably. South Korea plans to increase the proportion of renewable energy to 20% by 2029 based on the 7th basic plan for long-term electricity supply and demand. On the other hand, expanding the penetration of renewable energy sources is a new challenge for conventional power systems. Most renewable energy sources, such as photovoltaic and wind power, are intermittent, and thus difficult to control without a loss of power. In addition, the intermittent characteristics leads to an imbalance ofpower and load. This can be solved by combining renewable energies because the output characteristics of wind power and solar are different. A reliability assessment is an appropriate method for achieving the optimal combination of renewable energy sources. Therefore, this paper proposes the optimal sizing and location of renewable energy sources in a microgrid based on a reliability assessment. In addition, a stochastic method for LOLE (Loss of Load Expectation) is also proposed to evaluate the reliability. In this case study, optimal sizing and locations are determined by the minimum LOLE and power loss in an IEEE 34-bus system.
Abstract
