Technical Electrodynamics| Summary: | The impact of quality parameters of electrical energy to the economic characteristics of distributed generation systems, in particular on the profits from renewable power sources in isolated islanded MicroGrid, has been investigated. For this purpose, the Lagrange method was used to solve the task of profit maximization taking into account the limitations of the power supply system at different values of efficiency factors and nonlinear distortions of the AC supply load. The initial data for this task includes, in addition to the number of generators, loads and characteristics of their modes, also the forecasted values of consumption/generation and the local “conditional” cost of renewable energy sources. The result of the solution is the determination of generator coefficients and loads at each interval of the daily chart. The obtained coefficients determine on/off state or share of energy on which the power supply system element is working in the interval. These resulting values are used as the basis of the algorithm to control MicroGrid system by cost criterion. References 7, figures 1. |
