jailcd2018050: "Load Matching and Grid Interaction Performances of the Net Zero Energy Building with PV/fuel cell Hybrid System in Kitakyushu, Japan"

Abstract

Net Zero Energy House indicates a net power balance between building and grid over a time period, which shows a widely promotion potential in residential sector corresponding to the country’s political target. This paper classifies the detail electricity consumption and generation for a typical family with grid-tied PV/fuel cell hybrid energy system in Kitakyushu, the self-sufficiency ratio is about 46% over half year period based on the realistic monitored data. Then illustrates the seasonal load matching and grid interaction performances of the hybrid energy system, which are highly dependent on the production patterns of on-site generators and their correlations with load profiles. Fuel cell could effectively increase the on-site load cover ratio and reduce fluctuations in the net grid load in December. Aggregated proposed ZHE can effectively shape the grid load and cut demand during peak periods.
