How Energy & Power Systems Work

Grid Planning, Forecasting & Markets

Resource adequacy, forecasting, modeling, transmission/distribution planning and market structures.

Energy Systems Engineering

How technical, economic, environmental and reliability constraints are integrated across an energy system.

Energy System Integration

Connect generation, networks, storage, flexible demand and digital controls without treating them as separate projects.

Resource Adequacy

Why power systems plan enough supply and deliverability to serve expected demand under uncertainty.

Reserve Margin

A simple capacity-planning concept comparing expected available resources with forecast peak demand.

Transmission Planning

Why network expansion studies power flow, contingencies, generation changes and demand growth.

Distribution Planning

How local utilities anticipate feeder, substation and transformer needs as demand and DER change.

Power-Flow Modeling

A conceptual explanation of how network models estimate voltages, angles and transfers under steady-state conditions.

Energy System Modeling

How simplified mathematical representations help explore power-system behaviour and planning scenarios.

Ancillary Services

Why grids need frequency response, reserves, voltage support and other services in addition to energy.
