4.5 ADDITIONAL TECHNICAL REQUIREMENTS FOR PHOTOVOLTAIC SOLAR POWER PLANTConnection and parallel operation of Photovoltaic Solar Power Plant must meet the requirements of the protection function and interference prevention function of the system, as well as specific technical requirements for PLT EBT-based inverter as described in sub-chapter 4.1, 4.2 and 4.3.3. Figure 4.5 shows a simplified block diagram Photovoltaic Solar Power Plant is connected to the Distribution System. In addition to Solar Photovoltaic modules, the system's main components include the inverter, step-up transformer, and control devices as well as protection. Technology and design of Photovoltaic Solar Power Plant has undergone very rapid development in recent years. Four common types of configuration Photovoltaic Solar Power Plant is described in the following sections.

Figure 4.5. Simplified diagram of Photovoltaic Solar Power Plant Connection

4.5.1 CONFIGURATION CENTRALIZED INVERTERFigure 4.6 shows Centralized Inverter configuration which is relatively simple for Solar Power Generation Photovoltaics. This type of connection topology generating the most expensive, because it only has one centralized DC to AC inverters for photovoltaic panel strings which are connected in series and parallel to produce a certain voltage and DC current. Another weakness is system reliability problem, in the presence of interference or damage to the inverter, it will cause the entire plant stops operating.

4.5.2 INDIVIDUAL CONFIGURATION STRING INVERTERFigure 4.7 illustrates the Inverter String array where single series circuit of Photovoltaic panels are connected in series and string connected to single inverter and a single inverter for each string. Advantage of this configuration is that the string inverter has a maximum power point tracking capabilities. Maximum Power Point Tracking (MPPT) separately from each string of Photovoltaic used for reducing the loss of mismatch and partial shadows so it can increase energy production. The weakness of this configuration is required more inverter.

Figure 4.7. Individual String Inverter configuration

4.5.3 MULTI - STRING INVERTER CONFIGURATIONFigure 4.8 illustrates of Photovoltaic Solar Power Plant with Multi-String Inverter configuration. Some string with a separate MPP tracking system (using DC / DC converter) is connected to DC / AC general inverter for producing AC to the distribution system. This configuration makes it possible to optimize the efficiency of the operation of each string separately, and integration of various solar orientation to maximize energy production.

4.5.4 AC MODULES INVERTER CONFIGURATIONFigure 4.9 shows the configuration of the AC modules inverter where each Photovoltaic module has DC / AC inverter and Maximum Power Point Tracking (MPPT). Advantage of this configuration is very flexible design, so it can be easy to add more inverters in order to increase power generation capacity. Moreover, this configuration increases energy production by reducing energy losses from inverter mismatch and improve reliability. Weakness in this configuration is required additional charges for inverter and more complex maintenance.

Appendix B: Comparison of Requirements Engineering Guidelines and Rules Indonesia Electric Power

Distribution Electric Power Distribution Regulation issued by EMR in 2009 to establish general rules and requirements for security, reliability and power quality of the power distribution system. The rules governing the planning, operation, and connection of distribution system as well as the requirements of metering and billing settlement. This rule was drawn up with a focus primarily on conventional power plants without any special requirements for Renewable Energy Power Plant. Since then, a number of policies and government regulations have made its laws to promote and accelerate the development of renewable energy PLT small and medium scale.These guidelines are based on Electric Power Distribution Regulation to provideprotection and control functionality requirements are more detailed and specific in order to ensure the connection and parallel operation of PLT EBT does not adversely affect PLN Distribution System. Table B-1 is the ratio of grafting techniques PLT EBT requirements set out in this Code and Electric Power Distribution Regulation.
