EVOLUTION OF POWER SYSTEM PLANNING TO SUPPORT
CONNECTION OF GENERATION, DISTRIBUTED RESOURCES
AND ALTERNATIVE TECHNOLOGIES
Philadelphia, PA, USA – November 2 and 3, 2016
Colloquium organized by the CIGRÉ Technical Committee with the
CIGRÉ National Committee of United States
Leading Study Committee: C1 (System Planning and Economics)
Supporting Study Committees: A1,C5, C6
SUMMARY
This Colloquium is an initiative of the CIGRE Technical
Committee, supported by Study Committees C1, A1,
C5 and C6. It is sponsored by the U.S. National
Committee. It focuses on the role of reliability
standards and grid codes in defining the technical
connection conditions of generation equipment,
distributed resource technologies, demand response
technologies and storage technologies. The scope
includes transmission and distribution grids, down to
household voltage. Since generation remains
connected for decades, it must support the stable
operation of the grid not only today, but also in the very
different system of the future: Much more distributed
generation, much more fluctuating generation such as
solar and wind power, much smarter and more active
distribution, empowered customers and demand
response. These developments cause system
operators to call for wider frequency and voltage bands
in which generators should be able to stay connected,
but this can cause technical, market design and
economic difficulties. Applicability of strengthened
requirements to existing vs. new vs. refurbished plants
becomes an important question.
Experts from systems undergoing strong but different
kinds of development worldwide will discuss how their
reliability standards and grid codes are being adjusted
to fit for the future, and how they balance system needs
and connection costs. Generator and turbine
designers, manufacturers, owners, and experts will
share experience and knowledge on impact of new grid
codes on the design of generators and turbines,
limitations affecting upgrades and refurbishment of
existing generating units to comply to new grid code
requirements, the effects that a changing grid has on
aged existing generating fleet and total life cycle
costing, the effects on cost and designs of new
generators and turbines, design limitations
experienced and new concepts to overcome these
limitations. Developers of renewable generation
technologies, developers and aggregators of demand
response and alternative technologies such as storage
will share experiences with connection standards and
procedures and impacts of connection costs on
development strategies.
BACKGROUND
The electric power network or grid connects generation
units with customers. All network users and also the
grid itself need to adhere to reliability standards and
grid codes to maintain reliable service.
Network constraints are typically calculated by power
system planners and operators, and administered by
system operators. However, as the power system is
evolving, increased penetration of distributed
resources and alternative technologies has created the
need for planners and operators to learn from the
different customers connected to their network.
The rules associated with the network are defined in
reliability standards or grid codes. These are usually
binding rules, imposed either by regulators or
legislation, usually effectuated through the contracts
for connection which generators and customers must
enter into, which may differ from country to country due
to the varying characteristics associated with each
power system. For example, some systems are islands
or have weak connections to other systems and are
thus more constrained.
One example is the United States, where reliability
standards are established by NERC and the regional
planning authorities develop interconnection standards
that reflect regional differences while adhering to
higher level national standards. Another example is in
Europe, where ENTSO-E (European Network of
Transmission System Operators for Electricity) is
completing the development of a common set of grid
codes. These aim to manage large geographic energy
power flows on interconnected networks and between
interconnected and independent networks through
HVDC links, and to harmonize cross-border aspects of
country grid codes.
Power grids throughout the world are experiencing
unprecedented changes. The changes include
increasing connection of distributed resources,
renewable resources, demand response and storage
technologies. These changes are occurring rapidly and
are challenging the adequacy of current reliability
standards and grid codes. In some cases the existing
standards or codes are viewed as overly restrictive for
alternative or distributed resource technologies and in
other cases the rapid penetration of such resources is
creating reliability, economic or operational challenges
that are not addressed by existing standards or codes.
As these standards directly influence the design of
generation equipment, suppliers must provide input on
the physical limitation and cost implications for
installed generating equipment as well as the design
limitations on new equipment.
Therefore, there is a need to exchange views on the
developing design aspects and adequacy of reliability
standards and grid codes in this time of power industry
evolution throughout the world to share experiences
among the different network stakeholders to
understand their needs and to learn from each other
for the common benefit of all.
PARTICIPANTS
The Symposium is aimed at transmission, distribution
and generation asset owners, system planners,
regulators, researchers, generation developers,
renewable
resource
developers,
alternative
technology developers, and other network users. In
addition, manufacturers of generation equipment that
must respond to new network requirements are
encouraged to participate. It would be ideal if each of
the world’s regions were represented with at least one
grid code expert from the grid side and one from the
generation side.
