FEASIBILITY STUDY OF PARAMETERS OF HYBRID WIND-SOLAR POWER SUPPLY SYSTEM FOR THE INDIVIDUAL OBJECT

In remote networks from centralized electric power areas are arranged private cottages , workshops , radio and tele-communication stations, satellite earth stations , renewable energy to power such objects becomes almost the only solution to the problem . The random nature of renewable energy makes to combine two or more sources of power generation from renewable energy and electricity storage device to meet the needs of the consumer. The paper presents a comprehensive model of a hybrid wind-solar power supply system of a single object, which uses two complementary channel for generating electricity from renewable wind and solar energy, implemented using, respectively, the wind-driven vertical axis and the solar cell, battery and power system management, which is implemented on the controller. Hybrid wind-solar power system operates in the algorithm presented. Formed on the basis of the base hourly meteoro-logical data for the city of Lviv 2013 year and load individual cottage has developed a program that calculates the hourly energy balance between the consumer and a hybrid wind-solar power supply system for one year, and also allows you to select the optimal configuration of system elements with high economic and indicators of reliability. To assess the effectiveness of the calculated power loss probability criterion and the criterion of the relative excess energy generated. In this paper the cost analysis of all system elements was carried out and the price of 1 kW of electrical energy was calculated, depending on which elements is selected to the system configuration.
