Load scheduling is essential for optimizing power transmission on the system. The way to produce a stable electrical energy transmission system is to minimize transmission losses using between the moment of inertia and power on the generator. The generation noise is a description of the power losses on the transmission line generated when the power plant sends the load power. Transferring power from a high losses plant to a low losses plant. Rescheduling System can minimize transmission system losses. In this research, the scheduling result of this method is compared with the realization of scheduling of thermal generators from PT PLN (Persero) Sulselbar Central Disbursement and Control Center (P3B). This comparison aims to prove this method better than scheduling realized PLN, so that found also advantages and disadvantages method. After the research, this method produces a generation power that is close to stability, because the amount of power generated close to the power generation of PLN in fulfilling the same load demand remains with smaller transmission losses and cheaper fuel costs. The result of stable loading results in the efficiency of the electricity company so that it can reduce the operational cost of the generation and of course indirectly impact on the low cost of electricity production.

In the construction of a house, the model or design is often the main priority, while the electrical installation is not given much attention. As a result, the need for electrical energy is increasing rapidly. In addition, the increasing demand for electrical energy is also due to a lack of supervision and control over household electricity consumption. A simple solution to save energy while facilitating monitoring of electrical energy use is a system that integrated with various devices in the house. This system is also necessary because it can be controlled by the owner of the house remotely, namely by short message (SMS). This control system is controlled by an Arduino microcontroller as a control center connected to a device to turn on the lights. The microcontroller is connected to the GSM Shield which functions as a device that receives messages as short as those sent by the home owner. The contents of the message received by the GSM Shield will be read by the microcontroller and if the contents of the message are correct, the microcontroller can give instructions to the device to turn on the light.

The driver model is the decision-making and control center of intelligent vehicle. In order to improve the adaptability of intelligent vehicles under complex driving conditions, and simulate the manipulation characteristics of the skilled driver under the driver-vehicle-road closed-loop system, a kind of human-like longitudinal driver model for intelligent vehicles based on reinforcement learning is proposed. This paper builds the lateral driver model for intelligent vehicles based on optimal preview control theory. Then, the control correction link of longitudinal driver model is established to calculate the throttle opening or brake pedal travel for the desired longitudinal acceleration. Moreover, the reinforcement learning agents for longitudinal driver model is parallel trained by comprehensive evaluation index and skilled driver data. Lastly, training performance and scenarios verification between the simulation experiment and the real car test are performed to verify the effectiveness of the reinforcement learning based longitudinal driver model. The results show that the proposed human-like longitudinal driver model based on reinforcement learning can help intelligent vehicles effectively imitate the speed control behavior of the skilled driver in various path-following scenarios.

Energy saving can be maximized by rectifying the intermediate conversion processes involved during the utilization of solar energy. The system eliminates the transformation of electrical form of solar energy into another form by directly utilizing its electrical energy in the management and control of power supplies obtained from renewable (solar) and conventional (mains) energy sources. A current control scheme is presented in which current delivered by solar supply is used to control the current in mains supply in such a way that both currents are inversely proportional to each other. Any increment in solar current opposes mains current in the same proportion and vice versa. A balanced common physical output is resulted from the electrical load supplied by each source separately. A natural variation in solar radiation is utilized to fluctuate the solar current which is further used to change the mains current. Energy saving is maximized in this supply management by the optimal utilization of solar energy.

The traditional traffic light control system which applies timer control cannot adjust the light time period effectively when the vehicle flow changes. Based on the Cooperative Vehicle Infrastructure System (CVIS), this paper puts forward a scheme that traffic light can be changed adaptively according to the vehicle flow. It realizes the interactive communication among moving vehicles, roadside equipments and control center. As a result, the traffic light time period is regulated by the real-time feedback data.

In this paper, we analyze the methods of diagnosis and control the functional state of power oil transformers in electrical substations. Oil transformers are the most efficient converters of electrical energy, which is reflected in a higher efficiency in comparison with dry transformers. Oil transformers are designed to work with power grids in large industrial complexes where energy conversion is required to protect equipment from sudden voltage surges. The high loads associated with this work require timely diagnosis and maintenance of transformers. The article discusses the most commonly used methods for diagnosing deviations of the technical parameters of electrical substations in the process of their operation. The authors proposed a method of impedance series-parallel identification, which allows not only to determine the equivalent circuit of the power oil transformer, but also to diagnose possible malfunctions. Functional circuits of the device for impedance series-parallel identification of faults in power oil transformers have been developed.
