Different Types of Electricity Markets Modelled Using PLEXOS® Integrated Energy Model – The UK Balancing Market Example
| By Energy Exemplar
Electricity is a commodity that cannot be stored economically in large quantities. Therefore, generation must equal demand plus energy lost as heat when electricity is transported (transmission / grid losses) on an instantaneous basis. Otherwise the grid frequency starts deviating from its reference value, which can result in a system collapse. The design of electricity markets is adapted to deal with this particular property of electricity. Different types of electricity markets are arranged in a sequential order, starting years before the actual delivery and ending after the actual delivery.

Managing Risks and Optimising an Energy Portfolio with PLEXOS®
| By Energy Exemplar
Energy markets inherently exhibit far greater risk compared to traditional financial markets such as equities and bonds. Energy commodities in general display differentiating characteristics when compared to other asset classes which make conventional approaches to valuation, hedging and risk management a challenge for even the talented of risk managers. Market fundamentals play a larger impact with both supply and demand factors causing price behaviour to be very uncertain and at times volatile when compared to the price behaviour of other asset classes. Weather, infrastructure failure and fuel shortages coupled with rapidly changing demand for electricity on a daily or even hourly time scales make accurate price forecasting a constant concern. This white paper aims at analysing some of the quantifiable risks facing integrated energy companies and how fundamental optimisation software coupled with systematic and robust analysis can help decision makers manage risk and optimise their energy portfolio to retain their competitive advantage.

Incorporating the Capacity Market and Clean Power Plan into Resource Planning
| By Energy Exemplar
Resource Planning or Capacity Expansion is a process to find the best economical combination of the new resources to be built in the next 10 to 20 years to meet the anticipated load growth. There are generally two types of algorithms to achieve this.

Intelligent Grid - A Value Proposition for Distributed Energy in Australia
| By Energy Exemplar
In response to climate change, Australia is developing a suite of options aimed at delivering more efficient and sustainable low emissions energy. One solution is distributed energy, which provides solutions near the point of use rather than at remote locations.

Evaluating the Operational and Market Risks for Complex Energy Portfolios and New Energy Investments Optimisation in Europe employing the Power of Hybrid Integrated Modelling
| By Energy Exemplar
Today, it is widely accepted that the Global Community is facing significant challenges in the energy sector that stem from the combination of serious related environmental challenges and the emergence of a big variety of new cleaner (Renewables) and more efficient energy technologies during the last decade. The emergence of these new energy technologies though, is also accompanied by significant uncertainties on how they should be best integrated into existing energy systems, but also on how they should be best handled within the context of liberalised Energy Markets and Free Competition in the energy sector.

Energy Efficiency and Demand-Response in PLEXOS®
| By Energy Exemplar
The methodology for data mining is based on disaggregation at regional level followed by categorisation using classical clustering approach. Sources for historical and current values are prioritised by experience, state regulator publications, state-of-the-art revision. Trends will be created based on back casting and are subject to stakeholder review. Many regional system operators collect and use energy efficiency and demand response data in system studies. As well consultants, research centers and other entities regularly collect and tabulate energy efficiency and demand response data.

PLEXOS® Capacity Expansion Planning for Integrated Resource Planning
| By Energy Exemplar
The term 'capacity expansion' refers to the problem of finding the optimal combination of generation new builds and retirements and transmission upgrades (and retirements) that minimises the net present value of the total costs of the system over a long-term planning horizon. PLEXOS® simultaneously solves generation and transmission capacity expansion problem and a dispatch problem from a central planning, long-term perspective.

Stochastic Optimisation for Simulation of Electricity Markets
| By Energy Exemplar
For a Day-ahead Unit Commitment (UC), System operator must make certain commitment decisions 'now' e.g. for slow start thermal plant; and cannot perfectly anticipate certain variables such as load, wind, solar generation, or random outages.
