Polygeneration System

Some remote and rurar areas in Indonesia have low electrification levels and this poses a undermines their economic development potential. In response to the aforementioned challenges, it is necessary to develop an integrated energy system that produces multi-utilities (polygeneration) in producing energy to meet local needs. The aim of this work is to investigate the technical and economic analysis on a polygeneration system of a gas-fired power plant to produce electricity and heating, and to be integrated with an LNG regasification system for the utilization of cold energy as well. This polygeneration system is located in Manokwari District, West Papua. The polygeneration system was simulated using Unisim Design R390.1 to evaluate the technical performances and its economic analysis was done by using cash flow method with several business schemes, financial and fiscal incentives. The results showed that technically the polygeneration system is able to increase the efficiency of power generation system of a stand-alone power plant, from 32.9% to 59.7%. Economically, the polygeneration system can reduce the electricity tariff of a stand-alone power system from 19.32 US cents/kWh to 12.31 USD cents /kWh.

In the smart grid context, the article combines SEGS-VI solar thermal power station parameters to establish a solar thermal power generation system model. The thesis is based on the First and Second laws of thermodynamics. It uses the white box model analysis method of the energy system to calculate the solar thermal power generation system-concentrating and collecting subsystem, heat exchange subsystem, and power subsystem to obtain the subsystems dissipation of each process. Finally, the article uses the white box model analysis of the total energy system to treat the subsystems as white boxes, and connects them to form a white box network, makes a reasonable evaluation of the energy consumption status of the total energy system, and finds the weak links in the energy use process of the system. Provide a basis for system energy saving.

Telecommunications industry requires efficient, reliable and cost-effective hybrid power system as alternative to the power supplied by diesel generator. This paper proposed an operational control algorithm that will be used to control and supervise the operations of PV/Wind-Diesel hybrid power generation system for GSM base station sites. The control algorithm was developed in such a way that it coordinates when power should be generated by renewable energy (PV panels and Wind turbine) and when it should be generated by diesel generator and is intended to maximize the use of renewable system while limiting the use of diesel generator. Diesel generator is allocated only when the demand cannot be met by the renewable energy sources including battery bank. The developed algorithm was used to study the operations of the hybrid PV/Wind-Diesel energy system. The control simulation shows that the developed algorithm reduces the operational hours of the diesel generator thereby reducing the running cost of the hybrid energy system as well as the pollutant emissions. With the data collected from the site, a detailed economic and environmental analysis was carried out using micro power optimization software homer. The study evaluates savings associated with conversion of the diesel powered system to a PV/Wind-Diesel hybrid power system.
