Abstract
This paper built the simple simulation model of electricity demand and solar energy supply demonstrates monetary benefit derived from peak shaving and load leveling in operation of battery charging/discharging with photovoltaics in city blocks and communities.
As a result, we were able to get the conclusion of the following four points mainly. 1) The increment of the peak value 30 minutes for the average day and was limited to changes in gradual of about 10%, but it only obtained to reduce the 1.2% if you use an integrated manner across the district widely BT, case or, to operate together in a group applications BT, a significant reduction was obtained from BT users to combine together in a block unit. 2) Introduction to the total amount of PV-BT is the largest district in about 0.25 [kW/100m2] per unit area, the annual net benefits when changing the amount of introduction PV-BT is further reduced. 3)clarifing the effect of reducing peak load of distinction city that degree of mixing applications, possible to reduce peak by mixing the system residence, in order to away system and commercial system office time occurrence peak the results showed a quantitative reduction peak is low. 4) In block the system only commercial system and office are mixed, when shifted toward the power demand increases only the standard deviation, the effect of reducing peak load by BT is relatively high.
