IGREENGrid is a European research project
focused on identifying the best practices regarding
DRES integration issues.
the problem appears as a violation of the voltage limits and
grid congestion issues.
Numerous smart grid solutions have been developed to
address some of these resiliency challenges and to avoid disruptions to the grid. IGREENGrid is a European research
project focused on identifying the best practices regarding
DRES integration issues by analyzing a large number of
projects. In six successful large-scale demonstration projects, IGREENGrid has found practical implementations of
solutions based on the following functionalities:
✔ voltage control systems
✔ storage management
✔ generation forecasting, management, and curtailment
✔ load/demand management
✔ network reconfiguration
✔ islanding solutions
✔ anti-islanding systems
✔ network state estimation and network monitoring.
Based on the results of the analysis, there is common
agreement that the main type of disruptions in distribution
grids caused by a large penetration of DRESs are as follows:
✔ The violation of voltage limits on medium- and lowvoltage (LV) networks are usually addressed through
a diverse range of voltage control systems.
✔ The unpredictability of generation profiles of RESs
and the need for local balancing between distributed
(a)
generation (DG) and local demand are frequently
addressed using storage technologies and generation
forecasting and management, including curtailment
and active demand solutions.
✔ Faults and blackouts require grid systems to have specific intelligence to isolate the problem and recover
service as soon as possible. Network reconfiguration
and islanding operations are the most studied solutions
in research projects, but interesting aspects should also
be considered regarding anti-islanding systems, which
are related to avoiding undesired islanding following a
fault on the system and could present a safety hazard.
✔ Finally, in a more general approach, grid resiliency
can be improved by deploying monitoring and automation systems, reliable "analyze functions" such as
state estimation, optimal power flow, and congestion
forecasting solutions to predict and solve the problems
before they have an impact.
Voltage Control
Voltage control is widely considered to be the main concern
for distribution system operators (DSOs) when increasing the
amount of DG connected to the grids, which are not designed
for reverse power flow. Typically, about 75% (34.5 V) of the
voltage tolerance band (230 V ±10%) is intended to be used
for voltage drop caused by supply. Current developments
