A lossy electric power system area that contains thermal units and a pumped-storage (p-s) hydraulic unit is considered in this paper. The cost function, which is weighted combination of the total fuel cost and the total emission cost of the thermal units, in an operation cycle, is minimized under some possible electric and hydraulic constraints. The dispatch technique that is based on genetic algorithm considers minimum and maximum reservoir storage limits of the p-s unit, upper and lower active and reactive generation limits of the thermal units, upper and lower active pumping/generation power limits of the p-s unit, maximum transmission capacities of the transmission lines, and upper and lower limits of the bus voltage magnitudes in a considered power system. The proposed dispatch technique was tested on an example power system that has 12 buses with five thermal units and a p-s hydraulic unit. The same dispatch problem is solved via an iterative solution method based on modified subgradient algorithm operating on feasible values (F-MSG) and pseudowater price just for comparison purpose. It is seen that the solution technique based on the F-MSG algorithm and pseudowater price gives similar results with the proposed algorithm based on genetic algorithm.

Adequacy Criterion

This paper considers the optimization procedure of electric power system prospective structure with account made for two criteria: economic value (minimization of specific reduced energy costs for customers) and capacity adequacy (minimization of capacity shortage probability). The proposed procedure is based on genetic algorithm application. The results of procedure evaluation have been considered by the example of optimization of the structure of generating capacities within concentrated power system.

The Mathematical Model

A solution is presented for the problem of placing phasor measurement unit to identify the mathematical model of the electric power system in the state space. The criterion for complete observability of the Kalman dynamic system is taken as a basis. As a method of solution, we use the canonical genetic algorithm. The complete observability of the power system is ensured by the application of the observability rule in the form of a recursive test of observability. The proposed approach is demonstrated by the arrangement of synchronized vector meters in the Kaliningrad region power system.

<p>Now-a-days the Flexible AC Transmission Systems (FACTS) technology is very effective in improving the power flow along the transmission lines and makes the power system more flexible and controllable. This paper deals with overload transmission system problems such as (increase the total losses, raise the rate of power generation, and the transmission line may be exposed to shut down when the load demand increase from the thermal limit of transmission line) and how can solve this problem by choosing the optimal location and parameters of Unified Power Flow Controllers (UPFCs). which was specified based on Genetic Algorithm (GA) optimization method, it was utilized to search for optimum FACT parameters setting and location based to achieve the following objectives: improve voltages profile, reduce power losses, treatment of power flow in overloaded transmission lines and reduce power generation. MATLAB was used for running both the GA program and Newton Raphson method for solving the load flow of the system The proposed approach is examined and tested on IEEE 30-bus system. The practical part has been solved through Power System Simulation for Engineers (PSS\E) software Version 32.0 (The Power System Simulator for Engineering (PSS/E) software created from Siemens PTI to provide a system of computer programs and structured data files designed to handle the basic functions of power system performance simulation work, such as power flow, optimal power flow, fault analysis, dynamic simulations...etc.). The Comparative results between the experimental and practical parts obtained from adopting the UPFC where too close and almost the same under different loading conditions, which are (5%, 10%, 15% and 20%) of the total load. can show that the total active power losses for the system reduce at 69.594% at normal case after add the UPFC device to the system. also the reactive power losses reduce by 75.483% at the same case as well as for the rest of the cases. in the other hand can noted the system will not have any overload lines after add UPFC to the system with suitable parameters.</p>

Flexible AC transmission systems (FACTS) are a modern technology to increase controllability in power systems. This work presents an analysis of Interline Power Flow Controller (IPFC) which is a FACTS device. This device control and manage power flow in transmission lines. Supplementary damping controller is installed on IPFC Proportional Integral (PI) control. Power Oscillation Damping (POD) and Power System Stabilizers (PSS) contribute to power system stability.

General Plan

Basing on the principles of historicism and objective analysis the article examines the features and problems of implementing two state electrification plans: GOELRO plan adopted 100 years ago, under which the construction of local power plants in the Middle Volga region began, and the General Plan for the USSR Electrification, approved in 1932, which laid down the main solutions to radically redevelop the industry and agriculture of the region on the basis of using the sources of hydroelectric power, constructed on the Volga. In this regard, the historical and comparative method made it possible to highlight the main stages in creation and development of the power system of the Chuvash Republic, which since the mid 1950s has acted as a central a link in the country’s unified electric power system. The idea of creating energy hubs of the Volga Cascade, which in the years that followed provided the rise of industrial and agricultural production of the region, was based on the need for the priority development of the integrated power grid taking into account a strictly defined sequence of regional power plant construction, however, these aspects of implementing the electrification plans are not exampled in the domestic historical literature devoted to the reform of the energy industry. The article notes the pivotal role of scientific and technical cooperation between Leningrad and Cheboksary power engineers and instrument makers in solving the most complicated tasks in times of peace and during the war, it considers the contribution of Chuvash power engineers, who provided the construction and modernization of dozens of trunk transmission lines, which made it possible to fully implement the country’s electrification plan and to ensure energy security of the region.
