چکیده
This paper gives an overview of the current methods of calculation and optimization of active power reserve capacity. Methods used in the interconnected power systems of European countries and interconnected power systems of Baltic and Russia are described. The paper also represents the possibilities to utilize higher share of transmission capacity avoiding violation of thermal transmission limits in network elements.

Determination of Optimal Operating Reserves in Power Systems
The paper is devoted to optimization of reserves and reliability level. The four approaches presented will need deeper scientific research. 1. The sum of reserves’ costs and losses of consumers is minimized to the determination of optimal reserves. 2. Two-stage approach: 2.1. The sum of reserves’ costs and consumers’ losses is minimized to the determination of optimal requirements for reliabili...
متن کاملOptimization of electricity production capacity under uncertainty
The task of optimal long-term planning of electricity production capacity considering uncertainty intervals of the base, peak and intermediate loads, and multistage nature of the planning process will be tackled. Theoretical min-max approach to the problem will be given. Model uses dynamic programming and takes into account also constraints on structure of generating capacity and security of su...

متن کاملPPA Printer Firmware Design
A significant factor in Hewlett-Packard’s new Printing Performance Architecture (see Article 1) is the reduction of the processing power embedded in the printer. Using the host PC for all image formatting leaves only motor, print cartridge, I/O, user interface, command, and status functions to be controlled by the firmware. This results in significant cost savings by reducing processor needs an...
