Syllabus

Unit-1 :
Introduction to Power System Planning :
** Recent cost reductions and the increases in production of solar photovoltaics (PV) are driving dramatic growth in domestic PV system installations.
** Programs such as Solar America Initiative are setting out to make solar energy costcompetitive with central generation by the year 2015.

** As the costs decline, distributed PV becomes an increasingly significant source of power generation and, at some point, its further growth might be limited by the challenges of its integration into the power grid.

** To prevent these integration challenges from limiting the growth of solar PV installations and to maximize the overall system benefit, it is necessary to consider solar PV in all areas of power system planning, and to evolve the planning practices to better accommodate increased energy supply from solar PV.

** This report reviews the entire power system planning process, including generation, transmission, and distribution.

It discusses how the planning practices are changing to accommodate variable renewable generation, with a focus on future changes required to accommodate high penetration levels of solar PV and how to maximize the positive impact of other technologies such as load control and energy storage.

The report also proposes several areas for future research that will help evolve planning methodologies and enable easier and more-effective integration of solar PV.

** Electricity produced by solar PV currently is not cost-competitive with electricity generated by central stations, consequently solar PV has limited penetration in grid-connected applications.

As the technology develops and solar PV becomes more competitive, it is expected that it will start supplying residential and commercial loads at the customer‘s side of the meter.

This area of the power system has the highest cost of electricity, therefore it is where cost-competitiveness will be achieved first.

** Understandably, a sharp increase in the use of any one source of generation is likely to present integration challenges, but this especially is the case with the distributed solar PV for the following reasons.

** Solar PV is a variable source of generation—its power output depends on insolation and it is subject to potentially abrupt changes due to cloud coverage.

** Solar PV will evolve as a distributed source of generation first used to offset the connected load. As the penetration levels increase even further, two options are possible.

Energy storage could be used to ensure that no power is returned to the system, and the power could be sent to other loads in the system to avoid capital investment for dedicated storage.

The second option necessitates shipping power ―backwards‖ through a part of the electricity delivery network—the distribution system—and backwards power flow is not a design feature of present-day distribution systems.
