6 FAQs about [Power system planning and operation]
What is power system planning?
Power system planning is traditionally comprised of demand forecasting, generation planning, and transmission/distribution expansion. The results from all individual stages of system planning need to be coordinated in order to provide safe, reliable, and resilient electricity delivery.
What are power system planning and operational models?
These power system planning and operational models range from historical net load analyses and multiyear capacity expansion planning models, to hours-ahead to days-ahead production cost models, and subseconds-to-minutes dynamics models ( Sullivan et al., 2015, Sheble and Fahd, 1994, Palmintier and Webster, 2013, Miller et al., 2014 ).
How do power system planning models work?
For instance, planning models use hourly distribution data of supply- and demand-side resources to analyze future energy scenarios, but most power system phenomena occur in the range of seconds or minutes. Therefore, reliable and secure power system operations require ensuring the power balance at finer timescales.
Are power system planning and operational models suitable for flexibility assessment?
Power system planning and operational models applicable for flexibility assessment, including net load analysis, capacity expansion, production cost, and dynamic models, are reviewed in a comprehensive literature survey, with a focus on high solar and other variable renewable energy penetrations.
Who is responsible for power system planning?
The authority of power system planning belongs to local governments. Local governments are supposed to carry out power system planning according to local conditions. The rationality of power system planning should be enhanced by field investigation and environmental influence evaluation before system planning making.
What are the constraints of power system planning?
Long-term planning constraints. Table 4. Short-term operation constraints. Power balance between the supply and demand sides is the first prerequisite of power system planning. Initially, the electricity demand is merely satisfied by power generation from conventional energy resources, mainly thermal power, hydropower and nuclear power.
