Study on impact of wind power park integration on weak power systems : a case study on Mannar Wind Park in Sri Lanka

Abstract

Wind power is one of the largest sustainable alternative energy source used in the world for power generation. Though wind resource rich areas are available widely in Sri Lanka, excessive development of wind power plants would affect negatively on the system operations and system stability. Therefore, necessary power system analysis should be performed to determine the maximum wind penetration level into the national grid at an identified wind resource rich region. Since Mannar is identified as the prospective wind park development zone, steady state and dynamic system analysis were performed on the proposed transmission network for the year 2017 with four stages of Mannar wind development. The paper presents identified system constraints, recommended remedial actions and the final conclusion on the maximum wind penetration level from Mannar Wind Park for the year 2017.
