This study proposes a method to estimate the standard deviation (STD) of total power output fluctuation of high penetration photovoltaic power generation system (HP-PVS) dispersed in large area, so that the impact of HP-PVS on the load frequency control is discussed. First, by using the data of horizontal global insolation observed at 5 points in 25 km × 25 km area, the practical usefulness of STD...
Power output fluctuation of photovoltaic power generation systems (PVSs) may cause negative impact on the load frequency control of existing electric power system when the penetration of PVSs is quite large. For the cost-effective mitigation, the proper evaluation of apparent electricity load fluctuation property is very important, taking PVSs power output into account as negative load. Considering...
On constructing a microgrid, it is essential to balance capacity of photovoltaic power generation (PV) systems and storage batteries in accordance with a control target. In the present study, we constructed a simulation model of energy control system in the microgrid. By using this model, we investigated the acceptable capacity of PV systems according the capacity of NaS battery for keeping the target...
Power output fluctuation of photovoltaic power generation systems (PVSs) may cause negative impact on the existing electric power system when the penetration of PVSs is quite large. A micro-grid consisting of clustered PVSs and a battery system would be one of the promising measures to the negative impact of clustered PVSs, while the maximum power and storage capacity of battery system should be reduced...
Distributed generators (DGs) that use renewable energy sources have an unstable output and this can negatively affect existing electric power systems. To reduce this impact, we developed an energy control system for controlling the output from individual DGs that were installed in a microgrid. Controlling the DGspsila outputs enabled the power fluctuation at the point where the microgrid was connected...
