태양광과 풍력발전 등 분산전원의 대용량 발전이 기존 계통에 미치는 영향이 커짐에 따라, 계통 전압의 안정적인 유지를 위해 필요한 지원이 계통에 연계되는 분산전원들에게 요구되고 있다. 특히나 Low Voltage Ride Through (LVRT) 시에는 계통에서 탈락되지 않는 것은 물론이고, 계통전압 회복을 돕기위해 무효전력을 주입해야 한다. 이러한 사고 상황에서 계통에서 탈락되지 않고 계속적인 계통지원을 위해서는 빠르고 정확한 위상 추종이 필수적이다. 본 논문은 고조파에 강인하고 응답특성이 우수한 Low Pass Notch (LPN) PLL 기법을 LVRT에 적용하여 이의 우수함을 확인한다.

This article discusses the validity of selective/unilateral arbitration agreement that provides arbitration as one of several dispute resolution methods. The Supreme Court has held selective/unilateral arbitration agreement that is conditional invalidity since the judgement of 2003Da318 decided on Aug. 22, 2003: In the following judgements of 2004Da42166 decided on Nov. 11, 2004 and 2005Da12452 decided on May 27, 2005, the Court stated that the selective/unilateral arbitration agreement that stipulates to resolve a dispute through arbitration or mediation would be valid as an effective arbitration agreement only if a party elects and proceeds an arbitration proceeding and another party responses to the arbitration proceeding without any objection. The definition of arbitration agreement, the formation of selective/unilateral arbitration agreement, the summary of relative judgements and academic theories will be reviewed in order to examine the appropriateness of the series of judgements of the Supreme Court. Based on such reviews, this article will investigate the adequacy of the Supreme Court judgements from the perspectives of i) the principle of party autonomy, ii) the structure of dispute resolution methods, iii) legal provisions of Arbitration Act, iv) legal stability, and v) the policy to revitalize the use of arbitration. At conclusion, this article will suggest the change of precedents of the Supreme Court's judgements with regard to the selective arbitral agreement.
