Abstract

This paper addresses output smoothing control of an electric power system with multiple homes. The notion of home is a unit of small-scale power system closed to consumers. A home consists of local renewable-based energy source, energy storage, load, power conversion circuit, and control system. Output smoothing control aims to regulate the output power of a single home or coupled multiple homes to the outside of it and is expected to reduce the influence of fluctuating renewable sources to the outside, e.g. a commercial distribution grid. In this paper, we propose a batterybased algorithm for the output smoothing control and demonstrate its effectiveness in a practical,residential power system with two homes. In addition to the practical demonstration, by deriving a mathematical model for dynamics of active power flow in the controlled system and analyzing the model numerically and theoretically, we provide a guideline of tuning the feedback gain of the algorithm for a desired control response.
