Study Notes
Introduction to Power System Planning
-
The demand for power has been increasing over the years due to factors such as:
- Increase in population
- Heavy industrialization
- High economic growth and prosperity
-
Power System Planning is essential to meet current and future demand challenges in the electricity sector.
Objectives of Power System Planning
- To ensure the quality of supply, safety, and amenity
- To minimize total costs over the life of the system
Cost Components
- Fixed Costs: capital investment and their timing
- Variable Costs: continuing annual costs such as system losses and maintenance expenditure
Factors to Consider in Planning
- Growth of load in different areas
- Variations in the relative levels of the costs of materials and energy
- Increasing use of technical innovations
Planning Activities
- Determination of future network requirements (technical planning)
- Production of financial guidelines
Importance of Planning
- To strike a balance between technical feasibility and financial viability
- To undertake planning studies to:
- Draw up a list of expected major annual investments
- Allocate sums of money to cover future undefined technical schemes
