In Thailand, 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. At the present time, in addition, the emerging energy crisis resulting from an uncertainty price of crude-oil and the emerging global warming crisis results from carbon dioxide emission have drawn an attention about renewable energy all over the world including Thailand [1-2].One of the most effective solutions for Thailand is to promote the renewable energy usage in the rural area especially from solar energy and wind generation system. However, with the fast growing in wind power technologies, many concerns and focuses pay to this type of renewable energy in the country. Unfortunately, Thailand is considered as a country of low to medium wind speed profile with approximately wind capacity factor close to 30 percent. Therefore, in order to obtain the most efficient and effective wind generation system for rural household usage, the optimal design for a household scale wind generation should be governmentally supported and implemented. This paper, therefore, addresses to this issue and study result shows that the optimal scale of household wind generation system is 5 kW. with a proposed cut-in speed at 2.5 m/s while the suggested rated power at wind speed of 8 m/s. This proposed wind generation system can offer an Optimal Annual Capacity Factor (OACF) close to 30 percent.

Transmission Congestion Management (TCM) plays a significant role in power system operation under today's deregulated environment. Its two major functions are maintaining power system within security limits and collecting money from market participants paying back to transmission grid investors. TCM issue has been widely debated during the past decade. It is still an extensively discussed opened issue in the current competitive environment. In the United States, PJM with nodal congestion management (NCM) base on renowned location marginal price (LMP) and the Electric Reliability Council of Texas (ERCOT) with zonal congestion management (ZCM), are two successful stories of TCM under different operation schemes. Though PJM model is adopted in some developing countries where the processes of restructuring is still at the beginning phase, many social economical issues, such as advance in an information technology, energy security, social equity, price volatility, and the need to subsidize poor consumers, are necessary to be addressed before the establishment of TCM and settlement processes. Taking into account the above mentioned concerns, this paper proposes a TCM model for the electrical utility industry in Thailand during the transition period to the deregulated environment.
