Strategic Controlling

The dynamic development of the construction industry in Russia is accompanied by an increase in the complexity of ongoing projects and, as a result, an increase in the flow of information processed. It is necessary to manage a large number of different in intensity, direction, volume, flow patterns of informational, material and technical flows, as well as the flow of regulatory influences. In this regard, it is advisable to use a multi-level approach to planning the implementation of investment and construction projects in order to increase the efficiency and intensification of the construction industry. The article deals with the problem of regulation of phenomena and processes occurring in the space of investment and construction activities, by economic methods towards the realization of sustainable development goals. Options for the implementation of integrated control based on the investment program engineering control scheme are proposed, a flowchart of the algorithm for linking and implementing strategic controlling and operational management procedures within the framework of the integral control of construction projects of technically complex and unique objects is formed.

Proportional Integral Control

A novel control scheme for the dynamic voltage restorer (DVR) is proposed to achieve fast response and effective sag and swell compensation capabilities. In this control scheme, the proportional integral control is used to guarantee system dynamic performance and the repetitive control is used to improve voltage waveform quality. Compared to classical proportional integral control, DVR based on this control scheme can restore load voltage almost sinusoidal and shows better transient and steady-state responses when facing sag or swell conditions. The proposed control scheme has been verified by simulation on Matlab. Simulation results show that the control approach performs very effectively and yields excellent voltage regulation.

Proportional Integral Control

Wind energy is regarded as one of the oldest energy sources and has played a significant role. As the nature of wind changes continuously, the generated power varies accordingly. Generation of the pitch angle of a wind turbine’s blades is controlled to prevent damage during high wind speed. This paper presents the development and application of a fuzzy proportional integral control scheme combined with traditional proportional control in the dynamic behavior of pitch angle-regulated wind turbine blades. The combined control regulates rotor speed and output power, allowing control of the power while maintaining the desired rotor speed and avoiding equipment overloads. The studied model is a large-scale wind farm of 120 MW in the Gulf El-Zayt region, Red Sea, Egypt. The control system validity is substantiated by studying different cases of wind speed function: ramp, step, random, and extreme wind speed. The results are compared with the traditional combined control. The model is simulated using MATLAB/SIMULINK software. The simulation results proved the effectiveness of fuzzy tuned PI against traditional PI control.

Squirrel Cage Induction Generator

In this paper, the Squirrel Cage Induction Generator(SCIG) with distinct controllers to deal with a hybrid wind hydro scheme is employed. In order to reduce the output power fluctuations in SCIG, including energy storage in the battery, a fuzzy logic controller is proposed. This controller smoothens the reactive power to the supplied load by the wind generator. The proposed controller has faster convergence compared with usual PI controller under the presence of parametric variations and uncertainties. From literature, the control scheme as many controllers operates on the Proportional Integral control, which is easy to enforce and performs well under linear conditions of load. But the proposed controller operates not only linear load but also under nonlinear load conditions. Simulation results show the robustness of the proposed controller in eliminating the harmonics, efficiency and minimizing peak oscillations of the output voltage when compared with the conventional controller.

Load Conditions

Rural areas suffer from limited grid connectivity. Small hydroplants can provide electricity at a cheap cost with low environmental impact in these regions. Self-excited induction generators are widely used in hydroplants since they operate on a standalone basis because of the connection of capacitor bank that provides reactive power at no load. However, SEIGs suffer from poor voltage and frequency regulation. Thus, an electronic load controller (ELC) is connected across SEIG to regulate voltage and frequency. Generally, the control scheme for an ELC circuit is based on the conventional proportional integral control, which is easy to implement and performs well under linear load conditions. However, PI controllers handle nonlinearity poorly. This paper presents a fuzzy logic control (FLC) based control scheme for ELC in a constant power generation system (SEIG). The control scheme is designed and simulated in MATLAB under both linear and nonlinear load conditions. A comparison of both the controllers is conducted which highlights the superiority of the fuzzy logic control scheme.
