Low Efficiency

An increase in the share of renewable energy sources characterized by intermittent generation leads to a decrease in the quality of electricity and the need to balance the load on the network. The methods used today for balancing the load on the generation side, as well as the use of energy storage technology, do not always provide an effective solution to the balancing problem. This is especially evident when traditional generators are transferred from the base load electricity sources to the reserve ones. The main issue is the increased electric energy losses due to the low efficiency of the power storage technology. Using the most advanced hybrid power plant Gorona del Viento (El Hierro island, Canary archipelago, Spain), which includes traditional and renewable energy sources, as reference, we are describing the methods of balancing the load on the network, which includes balancing, both the electricity generation and consumption. Using the calculation models of the hybrid power plant operating modes, the possibility of implementing various load balancing strategies on the consumption side has been demonstrated, their features have been analyzed, their effectiveness in reducing energy losses has been demonstrated.

Hybrid Power Plant

The problem of control of a hybrid power plant of a car consisting of an internal combustion engine, a synchronous electric motor with permanent magnets and a synchronous generator is considered. The formation of the control effect is carried out taking into account the connection of the above objects with each other with the help of planetary transmission. The mathematical models of the three listed engines are nonlinear with several control channels. In addition, the principle of the hybrid power plant requires the simultaneous operation of these engines and, accordingly, the construction of the necessary interrelated control actions. To synthesize the laws of vector control of a hybrid power plant, the method of analytical construction of aggregated regulators (ADAR) is used. Within the framework of this method, it is possible to work with a complete nonlinear control object model. Unlike the traditional approach of constructing a separate stabilizing control for each control channel, this method uses co-control over all variables to transfer the object to the desired state. In this case,for a number of variants of control algorithms, the communication between the control channels is carried out not indirectly, through the control object, but directly formed in the regulator. In addition, the control law takes into account unknown external disturbances, which were compensated using the principle of integral adaptation. In this paper, one of the modes of operation of a hybrid power plant is shown during the acceleration of the car. First, only the electric motor works, as the car accelerates, the internal combustion engine is connected, and at high speeds only the internal combustion engine works. This mode of operation of the hybrid power plant allows using both engines in the most convenient range of angular speeds, which leads to an economical fuel consumption and a charge of the storage batteries. In addition, the second electric motor operates in the generator mode and transfers a part of the mechanical moment to recharge the batteries.

This article discusses the problematic issues of the study of the characteristics of wheeled plug-in hybrid electric vehicles (PHEVs) in accordance with the requirements of the Ukrainian classification of goods of foreign economic activity. Existing types of hybrid power plants are considered. We consider the problems that are solved by experts in automotive industry in the study of wheeled vehicles with hybrid power plants. Problems of determining the type of hybrid power plant of a wheeled vehicle, the principle of its operation, and, consequently, the influence of this on the determination of the code according to the UKT ZED (Ukrainian Classification of Goods for Foreign Economic Activity) are considered. Currently, in expert practice, there is no single approach in carrying out research to determine which characteristics the wheeled vehicle meets according to the Ukrainian Classifier of Goods of Foreign Economic Activity. In this article the main types and types of hybrid power units, the principles of their operation and the effect on the definition of the code under the UKT ZED are given. In relation to wheeled vehicles to one or another code under the UKT ZED it is necessary to determine the scheme of the operation of the hybrid power plant. In this case, hybrid power units operating on a parallel and serially parallel circuit should be classified in the code of code 8703 2 "Other vehicles with spark ignition internal combustion engine and crankshaft coupling" or 8703 3 "Other vehicles from an internal combustion engine with compression ignition (diesel or semi-diesel), and hybrid power plants that operate in a sequential scheme to the code number 8703 90 90 00 "other" as not falling under the requirements of the other the position of the booty on the principle of its work.

This paper proposes the reliability index of wind-solar hybrid power plants using the expected energy not supplied method. The location of this research is wind-solar hybrid power plants Pantai Baru, Bantul, Special Region of Yogyakarta, Indonesia. The method to determine the reliability of the power plant is the expected energy not supplied (EENS) method. This analysis used hybrid plant operational data in 2018. The results of the analysis have been done on the Pantai Baru hybrid power plant about reliability for electric power systems with EENS. The results of this study can be concluded that based on the load duration curve, loads have a load more than the operating kW of the system that is 99 kW. In contrast, the total power contained in the Pantai Baru hybrid power plant is 90 kW. This fact makes the system forced to release the load. The reliability index of the power system in the initial conditions, it produces an EENS value in 2018, resulting in a total value of 2,512% or 449 kW. The EENS value still does not meet the standards set by the National Electricity Market (NEM), which is <0.002% per year. Based on this data, it can be said that the reliability of the New Coast hybrid power generation system in 2018 is in the unreliable category.
