Combined peak shaving/time shifting strategy for microgrid controlled renewable energy efficiency optimization

Abstract

This paper presents a hybrid microgrid architecture (DC, AC and mix) to increase the energy efficiency of the system to different types of consumers, which can reduce the size and cost of those installations. Different modes of operation of the microgrid are discussed, based on the chosen architecture. The control strategy for increasing efficiency proposes a combination of a peak shaving algorithm with a time shifting algorithm in order to reduce the peak production in the battery and to move it to maximum consumption.
