Analysis of local power supply system power balance based on renewable energy sources and storage batteries

Abstract

In the article the approaches to parameter optimization power generation system, based on the wind turbines (wind turbines), solar power plants (SPP) on the basis of photovoltaic panels and small hydroelectric plants (SHP) located in the specified geographical location and is intended for power supply of enterprises of limited power. The analysis of their performance in various operating modes and certain characteristics of the system of accumulation . Researched system that includes a power generating components, the components of accumulation and discharge of electricity, and also the enterprise of limited power. Communication between components implemented by the controller (control system) that reacts to their current state. Input energy flows of the system of wind energy, solar radiation and water flow, which become respectively droelectric generators, photoelectric converters and generators toelectricity. The flow of electricity after the conversion and stabilization are directed to the consumer surplus in the energy storage system. The part of energy that cannot be accumulated, because of limited battery capacity or it exceeds the maximum value of the charging current turns into heat energy, for example, using a system of ballast resistors (SBO) and scatters. If the generated energy is insufficient, the control system receives the information signal about the need to connect to the electricity supply enterprises of the system of accumulation. The analysis of the balance of power in the auxiliary power supply of the enterprises of limited power. The proposed analytical relations and the mathematical model of a system of Autonomous power supply of the enterprise with the use of sources of alternative energy.
