Functions

EMarketOffer has three main functions:

To analyse and present key historical electricity Market data through a powerful set of information presentation tools in the Presentation Interface
To optimally dispatch and price the spot Market for situations of potential interest (generally termed Forecasting) and presenting the results through the Presentation Interface
To conduct Powerflow analysis for a defined network using given nodal demand and generation.

To achieve these main functions EMarketOffer must:

For Historical Periods

Calculate Powerflows using Generation and Demand figures
Interpret Transmission System data including dynamic changes such as:
- Circuit re-routing or retirement
- Circuit re-rating
- Outages
- Application of Equation Constraints

For forecasts of future periods (Scenarios, Forecasts and Powerflows)

Replicate the operation of the SPD Market clearance engine for both the energy and reserves market, to a high degree of accuracy and at high speed
Load large volume data sets directly from online databases or from file
Allow easy manipulation of historical Market and Transmission System data to quickly create new Forecast Definitions and thus conduct what-if scenarios analysis
Calculate Auto-SFT constraints that protect circuits from over-loading given an outage of one other circuit

The Presentation Interface provides the following analysis support functions:

Multi-featured Map
Flexible tabulation of data including separate floating Windows to monitor specific items of interest
Forecast Summaries to quickly identify the key features of a Forecast Run
Charting of Offer stacks, Demand Profiles and Supply Curves by user-definable periods
General purpose charting of any output variable
Single-period 'Scenario' mode allowing any Dispatch Factor to be amended and the effects seen instantly through an immediate re-dispatch
Marginal Analysis mode allowing the sensitivity of dispatch to changes in any Dispatch Factor
