Energy Systems

The energy systems research group consists of two divisions, which are Energy Management and Economics (EME) and and Renewable Energy and Microgrids (REM).

Energy Management and Economics (EME)

Energy management & economics is a broad scientific subject area which includes topics related to supply and use of energy in societies. Due to diversity of issues and methods applied and shared with a number of academic disciplines, energy economics does not present itself as a self contained academic discipline, but it is an applied subdiscipline of economics. From the list of main topics of economics, some relate strongly to energy management and economics:

  • Energy and Environment
  • Energy management and economic
  • Electric Utility Power Generation Economics

Energy management and economics also draws heavily on results of energy engineering, geology, political sciences, ecology etc. Recent focus of energy management and economics includes the following issues:

  • Tariff Policy
  • Climate change and climate policy
  • Risk analysis and security of supply
  • Sustainability
  • Energy markets and electricity markets - liberalisation, (de- or re-) regulation
  • Demand response
  • Energy and economic growth
  • Economics of energy infrastructure
  • Environmental policy
  • Energy policy
  • Energy derivatives
  • Forecasting energy demand
  • Elasticity of supply and demand in energy market
  • Energy elasticity measuring energy required to achieve GDP

Renewable Energy and Microgrids (REM)

Motto : “UI to become a leading university in renewable energy application in Indonesia”

REM research group was established in November 2008, and it is a part of Energy and Electrical Power Studies at Electrical Engineering Department, Faculty of Engineering – Universitas Indonesia. This research group is led by Dr.-Ing. Eko Adhi Setiawan, ST,MT.

Background

Research activities and new technologies in renewable energy is necessary to keep abreast with the latest development of technology. The acquired knowledge is beneficial to anticipate the future implementation of technology in the society. Renewable energy is one of the leading edge technologies which require rapid advanced technological research and development. University of Indonesia has declared itself as a research university. However, until recently the role of university in conducting research is still not up to the level of expectation. Therefore, a program is required to boost the research environment to reach the goal of the research university. Department of Electrical Engineering (DoEE) UI (University of Indonesia) has been backed by committed and academically strong academic staff majoring in various aspects of renewable energy.

Rationale

Renewable Energy can be particularly appropriate for Indonesia. In rural areas, particularly in remote locations, transmission and distribution of electrical power generated from fossil fuels power plant can be difficult and expensive. Producing Renewable Energy locally can offer available alternative. Interest in renewable energies has increased recently due to environmental concerns about air quality and global warming, a decline in the cost of the technologies for Renewable Energy and improved efficiency and reliability. Moreover the deployment of Renewable Energy technology in rural areas offers opportunities for the use of local natural resources, for employment, and ultimately for institutional capacity. Therefore we try to build a sustainable supply of Renewable energy by increasing Renewable Energy research activities, facilitating Renewable energy related innovations, and developing Renewable energy efficient technologies in accordance with the characteristics of natural conditions in Indonesia.

The focus of renewable energy research in electrical engineering department is to develop integration of energy system such as solar cell (photovoltaic), wind turbine, micro turbine and diesel generator which can operate in parallel with the electrical grid or in an intentional island mode. This system is suitable to be implemented in urban or rural remote areas in Indonesia. It is novel grid concept of a small-scale power supply network designed to provide power for a small community such as campus, BTS communication, village administration office and small hospital in remote area etc. In the future, it can be a solution part of energy demand problem in Indonesia.

Activities

  • Current project (until October 2009): Designing of Hybrid System for Sustainable Energy in Rural Area. National Strategic Grant 2009, funded by Directorate General  of Higher Education (DIKTI) Republic of Indonesia
  • Planning to develop Hybrid System (Under Review by DAAD and German Federal Ministry for Economic Cooperation and Development-BMZ) in order to achieve our focus research as mention above; we propose this planning to DAAD – BMZ to develop a small hybrid system laboratory. The configuration of hybrid system laboratory and its components is shown below. This configuration was design by SMA as a German partner discussion to develop small hybrid system laboratory.

Objective

  • To provide graduate students with high quality and advanced research coverage and facilities for their thesis and dissertation topics.
  • To provide facilities for UI researchers to keep up with renewable energy technologies development.
  • To conduct joint research and studies toward the development of Renewable Energy resources in order to address the increasing renewable energy demand, shortage of Renewable energy supply and to mitigate the negative environmental impact of renewable energy use.
  • To implement Renewable Energy technology that suitable for Indonesian condition

We also focus on how power electronics and drives interact with externally connected components or systems.

Electric Power Systems

Background

Electricity is one of the most important factors in our own civilization society. Every year, every month, every day or even every second, we use electricity for both fundamental and special activities. It also supports the developments of other technologies such as Information Technology (IT), computer and etc

Increasing in power demand, difficulty in adding generation units or power deregulation could affect the stability and reliability of power system. Thereby, in the future the electricity supply must face several problems.

In the modern society, it is not exaggeration to say that electricity is the base for Indonesian civilization. With the cleanness, convenience and good controllability of electricity, domestic power demand seems to increase; therefore, engineers should respond to such demand for high reliable and stable power energy. However, in the future, there is no guarantee that such demand is successfully responded even in Indonesian.

The location of power plant, resources such as oil and gas, environment problems from using fuels are considered to be the initial reasons. Although such problems can be solved, there are still some difficulties for the installation of power plant (especially the nuclear power plant) and the increasing demand cannot be responded. Even in the possible locations, it is limited in the areas that are far from high demand areas that are normally cities, and in power system perspective, power plant has to be connected to power system by the long distance transmission system, which tends to become unstable.

In addition, the power deregulation, recently introduced in some countries, could be considered to be one of the reasons. In such condition, Independent Power Producers (IPP), other than electric power entrepreneurs, can participate in the power market. They can generate electric power and sell to the consumers via power market. It can be considered as the reform of power electric field with the competition. In the perspective of stability and reliability, since many companies would like to sell their own generating electric power and they connect to the transmission system independently without paying attention to either reliability not stability of power system, the status and condition of power system tends to become worse and turn to insecure condition. At present, it can still be said that such influence is not clearly seen, but with the entries of many companies in the future, may becomes true and it needs the action to cope with that.

Rationale

From what mentioned above, it is necessary to improve and develop power system technology in order to respond to such demands with high reliability and stability in power system. A typical power system stability study consists of the following steps:

  • Make modeling assumptions and formulate a mathematical model appropriate for the time-scales and phenomena under study
  • Select an appropriate stability definition
  • Simulate and analyze to determine stability
  • Review results in light assumptions

Activities

In Power Systems Research Group, we realize such problems and actively research and focus on the how to improve the reliability, stability, and performance of power system that has been encountering several problems, affected from power deregulation and power demand increasing. Our activities in Power Systems Research Group are:

  • Seminar on Applied Engineering, department seminar, and so forth, plan for improving research skill of students
  • Submit papers and participate in Domestic Conference
  • Submit academic papers and participate in International conferences,
  • Discuss with another researcher from other countries, and then realize the problems or drawbacks in our own researches.
  • Actively participating in the meetings with manufacturers and companies is recommended. To realize the position of our own research in this field
