TL;DR: In this article, the authors propose a control system for adjusting an industrial load system to limit the demand of power while respecting the constraints of the load system, which is similar to our approach.
Abstract: The invention relates in general to control of the consumption of energy derived by an industrial user from a power supply system (electrical, gas or like commodity), and more particularly to a control system for adjusting an industrial load system to limit the demand of power while respecting the constraints of the load system.

TL;DR: In this article, a gas turbine power plant is provided with an industrial gas turbine which drives a generator coupled to a power system through a breaker, and the turbine-generator plant is operated by a hybrid control system having digital function capability during sequenced startup, synchronizing, load buildup and steady state load, and shutdown operations.
Abstract: A gas turbine power plant is provided with an industrial gas turbine which drives a generator coupled to a power system through a breaker. The turbine-generator plant is operated by a hybrid control system having digital function capability during sequenced startup, synchronizing, load buildup and steady state load, and shutdown operations. The control system also contains monitoring and protective subsystems which function through all stages of operation, with redundancy and permissive features which maximize turbine availability.

TL;DR: An easy-to-use method for evaluation of energy from power plants with different output and cost characteristics, based on the comparison of generation cost of the power station in question to the cost of generating energy with constant power, expressed by a value factor, and an analysis of the demand arranged to certain groups of daily utilization hours.
Abstract: This paper presents an easy-to-use method for evaluation of energy from power plants with different output and cost characteristics. The approach described takes into account the suitability of stations for covering a certain demand pattern. It is based on the comparison of generation cost of the power station in question to the cost of generating energy with constant power, expressed by a value factor, and an analysis of the demand arranged to certain groups of daily utilization hours. It permits an easy qualitative evaluation of the effect of different types of station on the development of overall generation costs.

TL;DR: In this article, the authors presented results of energy production cost calculations made for three sample power systems using a new, probabilistic technique which computes the statistical, expected value of the energy cost.
Abstract: The purpose of this paper is to present results of energy production cost calculations made for three sample power systems using a new, probabilistic technique which computes the statistical, expected value of the energy cost. These results demonstrate the importance of the effect of forced outages on expected, future power system energy costs. Unscheduled unit outages may increase calculated production costs by 2 to 5 percent. The calculations yield both expected cost values and loss-of-energy power system reliability measures and will provide information on the energy and power demand expected to be required for emergencies. These data are useful for system design. The paper illustrates the effect of the size of the available generating reserve on the system's probable loss-of-energy and expected production costs.

TL;DR: In this paper, the authors show that an increase in the installed capacity of the hydroelectric stations and their accelerated utilization under optimal conditions of power transmission from IPSS to UPSE will lead to an economy of the installed power at the thermal power stations of the IPSS and, accordingly, to a higher effectiveness of the construction of hydroelectric station and economy of expenditures for the development of power engineering in integrated power systems.
Abstract: 1. The power systems of Siberia and the European part of the country are characterized by different relative importance of the hydroelectric stations and density of the load curves. Thanks to this, on joining the systems it is possible to shift a part of the regulated power of the Siberian hydroelectric stations from the base-load (24-h) zone to the semibase (16-h) zone with a corresponding increase in the utilized capacity of the hydroelectric stations. Under these conditions the startup of the second lines at the Ust’-Ilimsk, Sayan-Shush’sk, and a number of other hydroelectric stations is economically warranted. 2. An increase in the installed capacity of the hydroelectric stations and their accelerated utilization under optimal conditions of power transmission from IPSS to UPSE will lead to an economy of the installed power at the thermal power stations of the IPSS and, accordingly, to a higher effectiveness of the construction of hydroelectric stations and economy of expenditures for the development of power engineering in integrated power systems.
