Transmission Planning with Battery Energy Storage Systems (BESS) as Non-network Solutions
The objective of electricity transmission network expansion planning is typically to determine the most efficient grid development options to balance generation with demand. Traditionally, this means planning for capacity expansion based on load and generation forecasts and is often supported by building new transmission lines across long distances from generators to load centres. Investment decisions have historically been driven by meeting technical requirements at the lowest cost. However, other issues such as social, environmental and land are quickly becoming prohibitive factors.
The use of Distributed Energy Resources (DER) allows load to be met on location. DER provide the opportunity for non-network solutions to minimize grid expansion. PVs and other microgenerators are now helping to reduce grid power consumption, but they bring their own set of challenges to the grid. It is difficult to predict their intermittent power output, adding variability and uncertainty to the operation of the power system. Popularly known as the enabler for the highly renewable future grid, the Battery Energy Storage System (BESS) is a necessary part of the DER family. Since it can be actively controlled, the BESS provides a way of smoothing the supply and matching the demand in the network.
Stability Study for Renewable Integration, North America
As renewable penetration increases in power systems around the world, utilities are required to proactively investigate the security and reliability of their systems to accommodate the new generation. A North American utility needed to address stakeholder interests in adopting more renewable generation and retiring conventional generation, while maintaining system stability. The utility needed a consultant to determine the level of renewable energy that could be accommodated by the existing system and help them present a sound investment approach that addressed stakeholder interests without putting the power system at risk.
PSC ran a comparative study between the client’s system model and jurisdictions in South Australia and Ireland experiencing similarly increased levels of renewable penetration in their systems. Our detailed knowledge of those systems from like projects expedited the analysis and ultimately reduced the study effort for the client. We shared lessons learned from how these jurisdictions responded to the retiring of conventional (synchronous) generation and adoption of more renewable (subsynchronous) generation as well as what other system settings were adjusted in order to accommodate them.
Distribution Automation Strategy Review
Distribution automation scheme applications in operation around the world improve reliability, voltage performance and network operational visibility. Across all the major vendors of advanced distribution management systems (ADMS) there is a common focus on automation applications covering situational awareness; network automation; business process automation; distributed energy resource management; and asset condition management.
PSC recently assisted a distribution utility client with an independent review of their automation strategy with a clear focus on improving supply reliability while meeting regulatory requirements for electricity safety and power quality. With network requirements changing rapidly, taking a broader view of automation is an opportunity for the client to prepare for changes in the future operation of distribution networks, as well as supporting further network operational improvements today.
PSC at CIGRE Canada
Meet the PSC team at the 14th annual CIGRE Canada Conference on Power Systems, hosted by Hydro-Québec in Montréal on September 16-19 2019.
CIGRE Canada is the Canadian National Committee of the International Council on Large Electric Systems, the leading international organization on high-voltage electricity generation and transmission. The purpose of the conference is to promote collaboration with experts from around Canada and the world by sharing knowledge and joining forces to improve electric power systems of today and tomorrow.
As a Diamond Sponsor, PSC is highly involved in the CIGRE Canada Conference. There are several opportunities to hear from our thought leaders and technical experts this year. Don’t forget to swing by our Booth #44 on the exhibit floor!
PSC Scholarship recipient Laura Harding and PSC New Zealand GM Peter Brown
2019 PSC Scholarship Awarded to Laura Harding
PSC has supported the University of Canterbury for more than 14 years. The PSC Scholarship was established in 2004 as a co-operation between PSC and the Electric Power Engineering Centre (EPECentre) to promote and support the education of power engineers and the study of power engineering as a field of excellence in New Zealand. The scholarship is open to students in their 3rd professional year who are focusing on power engineering subjects and have demonstrated excellence in their studies.
Our congratulations go to Laura Harding, this year’s PSC Scholarship recipient, who was selected from a very strong field of submissions based on her outstanding academic achievement combined with a strong focus on practical work experience. Laura has completed work assignments with Mitton Electronet and Electronet Transmission, and is currently the University IEEE Committee Chairperson for 2019. PSC New Zealand GM Peter Brown awarded the PSC Scholarship to Laura at the University of Canterbury in August.
PSC Welcomes New Staff
