posted on 2016-03-08, 16:40 authored by Francisco Gonzalez-LongattDC Independent System Operator (DC-ISO) is a
revolutionary concept; a single entity designed to coordinate, to
control and monitor the operation of the DC transmission system.
It will be responsible for ensuring the reliability and security of
the VSC-HVDC meshed networks in real-time and co-ordinate the
supply of and demand for electricity, in a manner that avoids
violations of technical and economic standards. This paper
proposes a simple methodology for optimal power flow (OPF)
allowing constant current operation in a series branch of the
VSC-HVDC network in order to cope with one the possible DCISO
objectives. One of the contribution of this paper is a
methodology that allows including new operator objectives as in
the OPF problem as a type linear equality constraints, it is based
on nodal analysis. Proposed methodology has been thoroughly
illustrated and tested with a simple 3-node MVSCDC system, and
results show the validity of the proposed approach.
