ANCILLARY SERVICES IN FRANCE

摘要

According to the law dated 10th February 2000, RTE ensures ancillary services (voltage and frequency control) are available and negotiates the necessary contracts with the producers.The working security of the power network lies at the heart of the responsibilities legally entrusted to RTE as operator of the French public transmission system. It states: "The public transmission system operator shall ensure the balance of electricity flows on the network at all times, as well as the security, safety and efficiency of the network, taking into account the technical constraints to which it is subject. The operator shall also ensure compliance with the rules governing the interconnection of the different national electricity transmission systems" (Law of February 2000, Art. 15.)Several mechanisms have been implemented to allow RTE to carry out its public service missions in an electricity market open to competition:1. an ancillary services contract, governing:the UCTE primary and secondary reserves,and the power plant primary and secondary voltage control reserves,2. a balancing mechanism, designed for the UCTE tertiary reserve,3. some specific regulations related to reactive energy at the interface with distribution networks,4. requirements or contracts without remuneration for "black start"(the capability to trip to house load is required for large generating units).
