|英文要約||Title:Demonstration Project on the Competitive Advantages of Power Storage Inverters for PV Generation Systems (Oshawa City, Ontario Province, Canada)
Experimental Demonstration for the Commissioned Business
Stable use of power is a critical issue for regions with an unstable power supply. Despite focusing on measures against power outages, they occur frequently in Canada. Tabuchi Electric considers the installation of PV generation systems with storage batteries is an effective solution for this issue.
Oshawa Power and Utilities Company (hereafter OPUC) which supplies power to 50,000 customers in the Oshawa City region, is positively considering introduction of the Tabuchi Electric solar inverter with storage batteries. Moreover, not only for OPUC, but for Oshawa City, Ontario Province, and Canada, we strongly hope to provide a solution for improvement of power in regions, and it is our expressed intention to work positively toward introduction of our rechargeable batteries for use with PV generation systems.
2. Overview of project
We, Tabuchi and OPUC, install the hybrid system which contains 5.5kW of grid tie inverter, 6kW of PV, 9.89kWh of Li-ion battery and monitoring equipment, hereafter "the system", to 30 homes in Oshawa city. We collect the operation data of the system and evaluate the effectiveness of the system. Finally we aim to establish the business model.
3. Result of this year
OPUC opened web page to introduce the system and over one handreds of homeowners applied to our project.
On Nov.20,2015 we held the opening ceremony and demonstrated actual operation of the system at the 1st site.
At the end of FY2015, we selected 30 sites and finished installation of 6 sites the other sites are under construction. We have started the data collection of 6 sites.
As a quick evaluation of 3 sites, the system operated in Economy mode, this mode stores in the storage batteries surplus PV-generated power during the daytime and discharges power in the evening and overnight to cover the household load.
However it was difficult to charge fully by solar generation only in winter season.
We would like to analyze and to evaluate operation next year continuously.
