In order to help combat climate change, Japan plans to introduce a large-scale photovoltaic (PV) power generation capacity. In this paper, we focus on reactive power in large-scale PV systems, first proposing a two-layered shunt capacitor (SC) scheduling method using multi-objective particle swarm optimization (MOPSO) and dynamic programming (DP). Using MOPSO, cost efficiency and reliability in power...
Japan plans to introduce a large amount of photovoltaic (PV) power generation capacity in order to help combat climate change. In this paper, we focus on reactive power in large-scale PV systems. First, we propose a two-layered shunt capacitor (SC) scheduling method using multi objective particle swarm optimization (MOPSO)—a meta-heuristic technique—and dynamic programming (DP). By using MOPSO, cost...
This paper analyzes system voltage oscillation and proposes a new systematic method for voltage stability control in the power system. Recently, renewable energy and distributed power generation have been introduced into power systems because of worldwide societal interest in environmental problems. However, renewable energies such as photovoltaic and wind power generation are unstable due to their...
In Japan, the introduction of large capacity photovoltaic (PV) power generation is planned to reduce environmental burdens. The Japanese government has set the target of 53 GW of PV power generation per annum by 2030. However, large penetration of PVs will cause several problems in power systems. One of these problems is that voltage values increase with the growth of PV usage. This increase is caused...
