The introduction of electric vehicles (EVs) has been increasing as well as photovoltaic generation (PV) systems. These introductions cause the voltage drop and rise on high-voltage distribution lines, so that voltage deviation will be out of the specified voltage range. As a countermeasure against this problem, the voltage control method with static Var compensators (SVCs) is implemented. However, SVCs are expensive and power losses on the distribution line increase. This paper proposes a novel voltage control method in which power conditioning systems (PCSs) output leading and lagging reactive power aiming to solve the above-mentioned problems. It is clarified that the proposed method is more effective in solution of these problems than compared with the voltage control method using SVCs.
