PLEXOS GUIDES 175GW RENEWABLE INTEGRATION BY 2022

NREL’s ‘Greening the Grid’ project concludes in India with a spectacular report.

  • Advanced weather & power system modelling identified impacts & actions
  • System balancing 100GW solar & 60GW wind is achievable at 15 min timescales
  • Coal fleet is flexible to manage variability & has a role to play
  • 160 GW of RE serves 22% of demand saving on fuel costs & emissions
  • New gas plant not needed for balancing while coal operates at half

Revolution in Hydro

The imminent release of a major update to PLEXOS will give rise to a new era in Hydro modelling with the arrival of a disruption to the 1970 SDDP methodology. The PLEXOS rolling horizon methodology offers multi-stage stochastic optimisation for long term hydro management at speeds 3 times faster than SDDP for the same high resolution.

AEMO 2017 Gas Statement of Opportunities study

AEMO 2017 Gas Statement of Opportunities study

Australian Energy Market Operator (AEMO) has released its 2017 Gas Statement of Opportunities (GSOO) study intended to assess the adequacy of gas infrastructure, reserves and resources to meet demand in eastern and south-eastern Australia up to 2036.

The 2017 GSOO highlights the increasing interdependencies of gas and electricity for reliable supply of energy, and the importance of planning across the entire energy supply chain to ensure energy security.

KEY FINDINGS from this study include:
  1. Declining gas production may result in supply shortfalls
  2. Maintaining system security is becoming more challenging
  3. Increasing electricity and gas prices may threaten commercial and industrial customers

MISO and PJM Release Joint CPP Planning Study Using PLEXOS

MISO and PJM Release Joint CPP Planning Study Using PLEXOS

Midcontinent Independent System Operator and PJM Interconnection have recently completed a joint study using PLEXOS of the implementation of the Clean Power Plan (CPP) in their combined footprint. The CPP has created a need for many electricity industry companies to undertake detailed emissions modeling as part of their long-term planning practices. PLEXOS provides this capability along with numerous other capabilities that establish its unique qualifications for this type of analysis. The study required the ability to model interregional economic interchange, transmission congestion, the inclusion of a diversity of generation technologies, production cost modeling, the simulation of energy markets, emissions restrictions and trading, and other compliance mechanisms such as energy efficiency.

The MISO and PJM joint study produced many insights. Two of these rise to the top of the analysis according to the study authors, namely:
  • variation in natural gas prices and state policies on resource economics are at least as important as state’s implementation of CPP rules, and
  • standardization of the energy efficiency across state lines may bring significant savings.

Regardless of the eventual implementation (if any) of the Clean Power Plan, many stakeholders in MISO and PJM and elsewhere across the United States are taking steps to address the core issues presented by the rule. The comprehensive modeling capabilities of PLEXOS make PLEXOS the ideal tool for this type of analysis.

Energy Storage for Smart Grids – 1st Edition

Energy Storage for Smart Grids

1st Edition

A great book containing an excellent chapter dedicated to using PLEXOS to simulate optimal hydro storage solutions for volatile wind energy driven electricity markets thanks to modelling by the Mid-continent Independent System Operator (MISO) in the US.

Description

Energy storage is a main component of any holistic consideration of smart grids, particularly when incorporating power derived from variable, distributed and renewable energy resources. Energy Storage for Smart Grids delves into detailed coverage of the entire spectrum of available and emerging storage technologies, presented in the context of economic and practical considerations.

Featuring the latest research findings from the world’s foremost energy storage experts, complete with data analysis, field tests, and simulation results, this book helps device manufacturers develop robust business cases for the inclusion of storage in grid applications. It also provides the comparisons and explanations grid planners and operators need to make informed decisions about which storage solutions will be most successful when implemented in operational grids.

Valuing California’s Technology Innovation in Energy

Lawrence Livermore’s ground-breaking study with PLEXOS

Lawrence Livermore National Laboratory (LLNL) recently published a study entitled THE VALUE OF ENERGY STORAGE AND DEMAND RESPONSE FOR RENEWABLE INTEGRATION IN CALIFORNIA.

Dr. Thomas A. Edmunds’ and numerous colleagues’ and collaborators’ work used PLEXOS to compute the economic value of several technologies designed to deal with the reality that growth in renewable energy resources will “increase the variability and uncertainty in electric generation resources” that power California’s grid. The stochastic unit commitment capabilities of PLEXOS were put to excellent use on LLNL’s High Performance Computing platform upon which 3 million core-hours of simulations took place.

Key findings of the report include
  • An estimate for the optimal sizing of four-hour energy storage technologies.
    • 900MW of storage for each of PG&E and SCE
  • A comparison of the economic value of three energy storage technologies.
    • CAES has the highest net-revenue per MW installed
  • The insufficiency of energy arbitrage to cover storage investment costs.
  • The value of ancillary services revenue to storage devices.
    • $100/kW-yr
  • The ancillary services impact of demand response programs.
    • 84 million $ per year for load following

The report offers many other valuable insights supported by extensive detail.

The study is vetting by the California Energy Commission and a technical review team assembled by DNV-GL.
