It is now proven that solar energy is more reliable when combined with other sources of energy. This course teaches the steps to follow in planning hybrid energy systems combining solar and diesel generators.
The course start with an introduction where the understanding of energy is fixed and hybrid energy systems defined; the course then continue with addressing the issue of load before describing the working principle and the sizing process of each of the component of hybrid diesel- photovoltaic energy systems. The course ends in presenting design and optimization tool and discussing the benefits of hybrid systems.
In this lecture, energy is defined and the law of conservation of energy explained. The lecture also address different energy carrier and state the difference between renewable and non-renewable sources of energy. Further in the lecture, solar energy and photovoltaic conversion are introduced as well as its impact on the social and economic development of the population living of the grid.
This lecture describes the general principle of the integration of renewable and non renewable energy within a single system. The particular case of solar photovoltaic energy and diesel generator is introduced.
These case studies are an excerpt of the brochure "Hybrid Systems" published by the Alliance for Rural Electrification (ARE)
Case study of a micro-grid combining PV and diesel generator in Nyumbani Village, Kenya
This lecture describes how load estimate should be undertaken and provide load profile tips both for systems supplying single users and systems supplying an entire village. The lecture proposes typical sources for each load pattern.
In this lecture typical rural villages load profile is described; their daily energy consumption is subdivided in small patterns and the lecture addresses the impact of the consumption patterns on the power generation sources with a particular focus on diesel generators.
This lecture present a simple and step by step approach for sizing a PV array.
This lecture covers the working principle of generators; their selection criteria and the factors influencing their power output quality. Further, a comparison is made between diesel generators and PV array.
This lecture present the factors that should guide the diesel generator selection for hybrid systems applications.
In this lecture, we discuss different types of batteries used for energy storage in off grid solar applications. Batteries selection criteria are also adressed
In this lecture, we describe the functionalities of inverters in hybrid off grid applications. The multifunctional inverter for mini-grid application is introduced; the difference between multifunctional off grid inverter and grid tie inverter is established and we give a picture of the ideal multifunctional inverter.
This lecture explain which values should be used for specifying an inverter.
In this lecture, we classify off grid solar software tools in three categories, sizing; simulation and micro-grid design. We explain how each the three category works
This lecture explains how by putting together the strength of generators and PV array hybrid photovoltaic/ diesel generator energy systems minimize weaknesses and become more reliable and cost effective energy solutions than generator alone or standalone photovoltaic system.
Mathy is the founder of Energy One Africa, a company founded with the goal of giving energy access to underserved low income consumers via pay-as-you-go. Energy One Africa's subscribers own a solar lamp after its full payment through small increments equivalent to their current kerosene lighting expense. Energy One Africa plans to reach 33000 subscribers in the rural Democratic Republic of Congo (DRC) between 2017 and 2019. He is also an IEEE Smart Village Ambassador, D-Prize winner and Tony Elumelu Entrepreneur
For ten years Mathy worked tirelessly to improve energy access for communities in Burundi, South Sudan, Rwanda and DR Congo. As both a challenge and an opportunity, Mathy demonstrated skills beyond his technical field in terms of project management, and the situation afforded him a chance to train and to efficiently build capacities in those he served. He takes a kin interest in understanding the real need of the communities he serves, especially their vital need for affordable energy. He believes that Energy Solution is the path to a better future for Off-grid communities.
His unique set of skills makes him a valuable asset for all his employers. In 2010, while employed by UNITECH in Burundi, he designed and conducted the solar electrification of Gasorwe and Bwagiriza refugee camps. The project consisted in designing and building 60 public lighting points, electrifying 12 classrooms, offices, and ONPRA residences (Burundian authority in charge of refugee affairs).
