英文要約Title: Verification of Grid Stabilization with Large-scale PV Power Generation Systems/ Verification of Grid Stabilization with Large-scale PV Power Generation Systems in Wakkanai site (FY2006-2008) FY2008 Annual Report This is the third year's annual report that contains the recent results of each research topic. In this year, 2MW of PV modules and a 1MW of NAS battery system were constructed. So the PV power generation system, some 4MW of PV modules and a 1.5-MW NAS battery system are in operation with connecting to 33kV power grid. For determination of PV output characteristics, 10 kinds of 10kW PV modules were installed in 2007. Each performance data under variable conditions including abundant snowfall and winter temperatures in Wakkanai site were collected and we analyzed the differences in characteristics between each type of PV module. The performance data was also used for the selection of modules that were installed in this year. In suppressing output fluctuations from PV system, for more efficient and effective operation of the NAS battery, several control algorithms of battery system for smoothing PV output are developed and examined in field test. It is expected to achieve the target of this project, more than 80% of fluctuation reduction. This project also studies methods for scheduled operation. In the scheduled operation, the station output is determined based on the PV output power estimated from the solar radiation forecast data. Mismatch between the scheduled station output and actual PV output are absorbed by the NAS battery. In this project, various forecast techniques and meteorological observation data are applied to refine the accuracy of the radiation forecasts. From the result of field test, our urgent mission is to develop optimal planning methods that are robust against the forecasting error and to improve the solar radiation forecast. In the harmonics generated from power station, although more than twenty PCS units were installed, our field harmonics monitoring and analysis showed that the harmonics inflow current from the power station is much lower than the allowable limit. Although no serious impacts of harmonics can be observed, field harmonics monitoring will be conducted continuously for further system expansions. For develop a simulation technology, we are studying the calculation flow and the selection of input and output data. For create the guidebook with guidelines for implementing large-scale PV power generation systems, we are studying each items in detail and writing drafts. We held the committee several times in this year, in cooperation with another NEDO PV project in Hokuto, to promote this project promptly and properly.
