配電電坮適正化を目的としたエージェントによる太陽光発電協調運用システム

摘要

太陽光発電（PV）は電圧上昇抑制機能により配電電rn圧の適正化を図っているが、多くのPVが連系されるとrn発電出力が減少する可能性がある。本研究ではこの問rn題を解決するため、配電系統に連系された多数のPVrnを、エージェント技術を応用して集中的に制御する方法rnを提案している。そして提案方法の適用可能性を、計rn算機ネットワークを用いて検討している。%This paper discusses photovoltaic generation power decreasing problem which are caused by the interconnection of many photovoltaic systems on distribution networks. The existing photovoltaic system can control the voltage at the interconnection point within the specified voltage limits. However, the photovoltaic system cannot generate maximum active power because of the voltage control scheme when a lot of photovoltaic systems are connected on the networks. To overcome this problem, we study a centralized voltage control scheme of photovoltaic systems, In this control scheme, voltage control scheme of individual photovoltaic systems are determined by the voltages, output of photovoltaic systems, and prediction of generation power at all interconnection point in the networks. And this control scheme is implemented by using multi agent technology. Furthermore, by building this centralized control scheme in authors made prototype model system, the generation power can be improved by application of the centralized control scheme.
