The emerging global warming crisis results from carbon dioxide emission has drawn an attention about renewable energy all over the world. Thailand is a developing country located at the heart of Southeast Asia with almost 70 million of population as of 2008. The ESI structure under the government of Thailand has been managed by the Electricity Generating Authority of Thailand (EGAT), Metropolitan Electricity Authority (MEA), and Provincial Electricity Authority (PEA) for almost 50 years. According to the Power Development Plan (PDP 2007), during the year 2007-2021, the government of Thailand plan to have the most economic power generation resources yet reliable and least environmental impact. To achieve those goals, there are three strategic plans which are to import power from neighboring country, to promote the renewable power generation from the public power companies, and to have a variety on power generations resources. This paper discusses the biomass power generation development in Thailand. System overview processes and biomass fuel consumed for the electricity production process are also presented.

    ABSTRACT: This paper presents an impact study of energy storage on a micro-grid system consisting of a very small power producer of a biomass type. The energy storage used in this paper is a battery bank. It comprises a combination between shunt and series battery cells in order to implement a sufficient battery storage system. To verify the simulated battery storage system, one day operation of an electric power distribution system was tested. This simulation was performed using MATLAB software in order to support and also to balance the energy exchange between the generation (drawn from both substation and renewable energy plants) and the power demand of the entire system. With the energy storage plant of battery banks, a simple 6-bus test system with a total power generation of 6 MW is situated for test. Considering of four test cases (case 1: without energy storage installation and neglecting power losses, case 2: without energy storage installation but considering power losses, case 3: with energy storage installation but power losses neglected, case 4: with energy storage installation and also considering power losses). Power transmission losses used in this paper can be determined by using Newton-Raphson power flow solution method. The simulation of the test system was carried out by performing one day simulation with energy storage and energizing stored energy by using an appropriate algorithm. The results showed that the system with energy storage can lead to efficient energy usage and power loss reduction.
