4. Toronto, Ontario - Cigre Canada Annual Membership meeting, October 4, 2009 SC C1 – System Development and Economics - Scope The scope of SC C1 is to study economic and system analysis methods important for the development of power systems and to assist utilities to find the best solutions in various evolving, competitive and unbundled conditions in the context of the overall energy supply system and with social and environmental considerations. The main areas of attention are: - Methods and tools for power system static and dynamic analysis - Planning predicaments and methods in competitive and regulatory structures - Progress and new approaches in application of power system planning criteria and reliability (security and adequacy) assessment - Capacity enhancement by use of risk-based security assessment and advanced information, communication and power-electronics technology for improving system stability and dynamic performance - Future dependence, requirements and economy of ancillary services for frequency and voltage control and other system needs - The impact of pricing and tariff methods for transmission services on system development. - Asset management strategies in the definition of optimal policies - Planning issues related to long distance transmission and international interconnections. System planning issues in newly industrialised and developing countries - Impact on system development of new solutions and technologies in fields such as generation and demand side management (DSM) Vancouver, British Columbia – CIGRE Canada Annual Meeting, October 17 – 20, 2010
