Abstract

The chapter proposes to approach the problem in the following ways: assess the problems in the existing power system, analyze the current state of the RES using, and determine the existing ways of computer modeling of the grid. The chapter also discusses the topicality of renewable energy use in the construction of distribution grids and the ability to model their work. It explores issues including current research attempts to identify the existing methods, which can be applied in the Decision Support System (DSS) for calculation and evaluation RES. The problem of making decisions for energy saving in district heating requires such measures as energy audit and planning. These activities require monitoring the current energy consumption in real time.

Background

According to the national power company Ukrenergo (Safe Mode the work of DEC Ukraine, 2014) the Unified Energy System of Ukraine is represented by thermal, nuclear, hydro, wind and solar power units which are interconnected in the parallel operation. It produces and distributes heat and electric power. Units for power production include (Ministry of Energy and Coal Industry of Ukraine, 2013):

  • 5 electricity generators that produce electricity at thermal power plants;

  • 4 nuclear power plants;

  • 12 hydroelectric power stations;

  • 27 local, mostly private, energy distribution companies;

  • 104 thermal powers in larger cities;

  • 4 solar power plants;

  • 5 wind farms.

At the end of 2010 the power production in Ukraine reached 191.5 billion kWh, 47.27% of which came from nuclear power plants, 36.89% came from thermal generation, and approximately 7% came from Thermal Power Plants (TPP) and Hydro Power Stations (HPS), a small part was produced from the RES (Consulting Company NIKO, 2014).

Units for heat supply are:

  • 250 cogeneration plants;

  • More than 35000 centralized boiler plants;

  • Industrial boiler plants of large individual enterprises;

  • Individual heating systems of the apartments.
