Long-term energy system planning considering short-term operational constraints

  • Long-term planning models give an insight into possible energy scenarios and do not examine technologies in detail.

  • Renewable energy sources have spatial and temporal intermittency that causes challenges for short-term system operations.

  • Including operational details of generators directly in a planning model reduces intricacy of handling separate models.

  • Operational constraints increase usage of conventional generators and reduce overall capacity needs in planning model.

Cleaning Up the Act

Find out how Shameela and members of her community in Andhra Pradesh are ensuring sanitation for all under CSTEP’s inclusive framework. Integrating gender into sanitation, the framework, which was implemented through a consortium including CFAR and ASCI, put an end to open defecation in three towns of the state, while achieving gender equality, clean water and sanitation.

An empirical model for ramp analysis of utility-scale solar PV power

Short-term variability in the power generated by utility-scale solar photovoltaic (PV) plants is a cause for concern for power system operators. Without quantitative insights into such variability, system operators will have difficulty in exploiting grid integrated solar power without negatively impacting power quality and grid reliability. In this paper, we describe a statistical method to empirically model the ramping behavior of utility-scale solar PV power output for short time-scales.

Roadmap for Karnataka's Power Sector - Vision for 2021-22

The State’s capacity addition plans seem inadequate to meet projected demand in the next 5 years. If the current situation continues, the State is likely to face about 21-26% annual energy shortfall (12,000 – 18,000 Million units) and 15-17% peak shortfall (~ 2000 MW) in the short-term (2 years) and 13-8% (~10,000 Million Units) and 16% (~2500 MW) in the medium term (5 years). This is after  accounting for all likely capacity addition. This implies that the State will have to rely on widespread load shedding or rely on short-term power purchases.

Mobility & Urban Poor

Policy should focus onthe disaggregated needs of the public system, integrating land use and transport.Improvements to Non-Motorized Transit facilities with emphasis on importance of pedestrians Improvements to the bus system includes pricing, timing and awareness of service quality Social impact studies (positive & negative) of major projects should be mandatory, inclusive and participatory.
