System simulation software is an essential tool to analyze and compare possible system combinations. The objective of the control strategy is to achieve optimal operational performance at the system level. Inefficient operation of the diesel generator and “dumping” of excess energy is common for many RAPS, operating in the field. Component maintenance and replacement contributes significantly to the lifecycle cost of systems. These aspects of system operation are clearly related to the selected control strategy and have to be considered in the system design phase.
The bi-directional inverter can charge the battery bank (rectifier operation) when excess energy is available from the diesel generator or by the renewable sources, as well as act as a DC–AC converter (inverter operation). The bi-directional inverter may also provide “peak shaving” as part of a control strategy when the diesel engine is overloaded. In Fig. 30a, the renewable energy sources (RES) such as photovoltaic and wind are coupled on the DC side. DC integration of RES results in “custom” system solutions for individual supply cases requiring high costs for engineering, hardware, repair, and maintenance.
29). Advantages: The inverter can generate a sine-wave, modified square-wave, or squarewave, depending on the particular application. 29 Switched PV-diesel hybrid energy system. The diesel generator can supply the load directly, therefore improving the system efficiency and reducing the fuel consumption. Disadvantages: Power to the load is interrupted momentarily when the AC power sources are transferred. The engine-driven alternator and inverter are typically designed to supply the peak load, which reduces their efficiency at part load operation.
