NICOP - Distributed Generations and Load Monitoring Platform for Community Power System
Abstract
Due to the increase demand for energy to support the ever growing economy around the world. Therefore, every country must find ways" to be self-sustaining in the energy area by exploring the use of renewable energy. Renewable energies are generally site specific and depending on the natural resources of the sites. Most countries are moving toward renewable energy as distributed generation sy"stems or localized power production. Therefore, in one community, several distributed generation systems (DG) are being installed t""o produce electricity such as PV rooftop, PV ground, Biomass gasifier/boiler, Biogas generator, Wind turbine and Small hydro s""ystems. Typically, these systems are standalone power production system and are not monitored and linked together. Moreover,"" each system may have different protocol in power production and monitoring. However, it is necessary to have flexible monitoring s""ystem for various DG systems in order to know how much power is being produce and how much is being used. With these information, ap"propriate energy management system can be made to fully optimized and utilized the renewable energy power in the community.In this" work, the decentralized community power system with PV as the main energy sources will be designed and integrated with other" DGs depending on the local resources. The DGs and loads monitoring platform will be studied and developed in order to obtain the appropriate protocol for the integration of various renewable energies in the community. Linking the small DGs together can provide optimal usage of existing renewable energy DGs and newly installation DGs for small community application or small military base application. The monitoring system will be designed for collection and system operation observation." The system will provide real-time monitoring via internet connection for environmental condition, power generation, and power consu""mption. Web application will be designed, developed and run on a server. Therefore, client could access the data via web browser suc""h as Internet Explorer, Google Chrome or Firefox in real-time. Using the existing web platform is the flexible and cost effective wa""y for the application. Web Application could be divided in 3 main parts: database, code program and display.The proposed site to d"evelop and evaluate the DG and load monitoring platform for community power system will be at the Chiang Mai World Green City (CMGC). CMGC is the testbed for community power of the small rural communities. It uses all renewable energy to power 20 small buildings which are connected by DC and AC microgrid system. CMGC is developed from over 35 sustainable energy research and development proj"ects. CMGC is also the model and technology transfer center for various renewable energy systems, energy conservation and applicatio""ns. The power generation data will be collected from Grid-connected AC system (PV 702 kW, diesel generator 100 kW), Stand-alone D""C microgrid (PV 25.5 kW, battery 105.6 kW, diesel generator 40 kW), Stand-alone AC microgrid (PV 25 kW, battery 100 kW, PV rooftop 3"".5 kW, biomass gasifier 20 kW), Stand-alone PV 2.64 kW (Bus stop), PV farm pumping 3 kW and Biogas power plant 1.5 kW. Community po""wer generators will be evaluated according to standard method, e.g., IEC 61724. Performance ratio (PR), array yield (Ya), Final yiel""d (Yf), Capture loss (Lc), System loss (Ls) will be calculated to determine system performance. In this project, batteries will be"" used as power storage. Net energy to storage (ETSN,~) and Net energy from storage (EFSN,~) will be calculate to determine the relat""ion between power generators, batteries and loads. The load monitoring are 20 small building units including 10 houses, 4 conferenc""e halls, 3 offices, 1 minimart, 1 restaurant and 1 coffee shop. All loads will be monitored and evaluated for power consumption. The" obtained
