Energy management system for a smart microgrid -

Abstract

In this thesis an energy management system of a microgrid is developed based on quadratic programming. The microgrid contains renewable energy resources, a battery and a diesel generator. The sizes of the components are changed to present a somehow maximized gain from the microgrid. The battery and the diesel generator sizes are found by trying a big size and checking if it is enough or if it is too big for the project. On the other hand, the number of photovoltaic modules to be used is found by finding the net present value (NPV) of the project while changing the number of modules until reaching the maximum NPV. A case study will be presented of a village in Lebanon. Different available resources are considered and the costs of the fuel, operation and maintenance, and the penalty cost incurred due to pollution are found. A comparison is done between various scenarios in the village. The levelized cost of energy and the net present value for each of the scenarios is found to check the techno-economic viability of the project from the customer and from the investor’s point of view. Benefits due to pollution reduction are also considered by taking into account the penalty costs of pollutant generation. This project can give an idea of how beneficial it may be if the same microgrid concept presented in this thesis is applied over other villages and cities in Lebanon.
