no. 1 approach

[0058] figure 1 The overall structure of the electric power supply facility using the renewable energy of this invention is shown.

[0059] exist figure 1 In the figure, the dotted lines represent conventional power generation facilities using solar power generation arrays 1a to 1d, and each of the solar power generation arrays 1a to 1d having a plurality of solar power generation panels has an output of 100 [kw]. Each of the solar power generation arrays 1a to 1d is connected to an AC wiring 3 via a power conditioner (hereinafter referred to as "PCS") 2a to 2d, respectively, and is connected to the outside via a power distribution transformer 4 and an output AC wiring (existing AC wiring) 5 microgrid power supply6. The output of each of the above-mentioned solar power generation arrays 1a-1d is 100 [kw] respectively, and is converted from DC to AC 380V by the above-mentioned PCS2a-2d and stabilized. The voltage is boosted and supplied to the external microgrid power supply...

no. 2 approach

[0159] Next, pass Figure 6 , Figure 7 A second embodiment of the power supply facility of the present invention will be described.

[0160] Such as Figure 6 As shown, a plurality of charging devices 24 for electric vehicles are connected to the AC wiring 5 of the external microgrid connected with the power supply equipment of the present invention. In addition, it is connected to each charging device 24 via a switch 25 a of a smart meter 25 .

[0161] The remaining battery level sensing unit 42g of the above-mentioned EMS19 (2 system, refer to Figure 20 ) monitors the BMU 22b of the 2 systems (not the largest output side, the system that shares 50 [kw] in the above-mentioned first embodiment), and always checks the battery capacity of the 2 systems. Usually, since the battery remaining capacity of the 2 systems is sufficient, the EMS 19 sends a signal that charging is possible to the above-mentioned smart meter 25 via the SMC 23 .

Abstract

The present invention is configured such that a power supply facility is provided separately to a grid 1 and a grid 2, said power supply facility comprising a power generation device using renewable energy, a power storage device, and a grid connection conversion device that converts output from the power generation device and the power storage device to alternating current and is connected to an existing alternating current distribution line. A monitoring / control device allocates a requested amount of power to the maximum-output grid 1 and the remaining-power grid 2, supplying of the requested power is handled by the respective power supply facilities of the grids, and the total of the output of the power supply facility of the grid 1 and the output of the power supply facility of the grid 2 is output to the existing alternating current distribution line as the requested power. The monitoring / control device carries out control for alternating the operation of grid 1 and grid 2 everyday.

Description

technical field [0001] The present invention relates to a power supply facility for supplying stable power using renewable energy such as solar power generation. Background technique [0002] Conventionally, a small-scale energy network, a so-called microgrid, in which natural energy sources such as solar power generation and wind power generation are dispersed and equipped with consumption facilities has been put into practical use. [0003] In such facilities, output fluctuations due to natural energy supply sources such as climate fluctuations will adversely affect the power system connected in series. Therefore, in order to compensate for the above-mentioned output fluctuations, a power storage device is installed to charge and discharge, and the supply and output are suppressed.
