Abstract
The paper proposes an algorithm to optimize the structure and the choice of capacity of wind and diesel power units of the combined power plant, depending on the wind energy potential and electricity consumption of electrified facility. The algorithm is based on mathematical models of technical and economic characteristics of wind and diesel power plants as well as an optimization method of coordinate descent. The algorithm takes into account the structure of the combined power plant, changing modes of its operation, construction and operation costs of the power facility. The objective function of the algorithm is to minimize the cost of electricity generated.
Highlights
A large number of papers are devoted to the issues of simulation and optimization of the power supply system (PSS), using renewable energy sources (RES)
The diesel power plants (DPP) structure and composition are determined by the facility energy needs, recommendations to ensure energy-efficient modes of diesel generators and practically does not depend on the wind power plant
It should be noted that WDPP structure recommendations, depending on the average wind speed, can be adjusted according to the achieved economic project indicators
Summary
A large number of papers are devoted to the issues of simulation and optimization of the power supply system (PSS), using renewable energy sources (RES). Let us note the works [1,2,3], which significantly contributed to designing software packages for automatic optimization. The most common are as follows: HOGA – Hybrid optimization by the genesis algorithm (Spain), HOMER – Hybrid optimization modeling software (USA), HYPORA – Hybrid power optimized for rural / remote areas (USA). Mathematical models of optimization software packages are implemented by various means of computer programming: C ++, MS, Excel, JAVA, etc. The advantage of these optimization software packages is the possibility to solve optimization problems of power facility with an optimal ratio of generating units having different physical properties. The presented software packages feature a convenient interface, which simplifies their use
