Objective
THE MAIN AIM OF THIS CONCERTED ACTION GROUP IS TO DEVELOP A STRATEGY FOR THE CONTROL AND MANAGEMENT OF BATTERIES IN THE PV PILOT PLANTS.
Research undertaken to identify problems experienced in battery control and management in photovoltaic pilot plants is described. The battery problems were due to system design, poor maintenance procedures and in some cases to battery design. The practical experience from the pilot plants shows that existing photovoltaic systems cannot be accepted. However, the experience does show that the battery in a poorly designed system can operate maintenance free for up to 3 years.
THE MAIN ACTIVITIES OF THE PROJECT WILL BE:
-COMPILING GUIDELINES FOR THE OPERATION AND MAINTENANCE OF BATTERIES IN PV SYSTEMS
- DEVELOPING A RELIABLE STATE-OF-CHARGE INDICATOR
- DEVELOPING A BATTERY MODEL FOR CONTROL STRATEGY ANALYSIS
- TESTING BATTERIES TO IDENTIFY THE COMMON CAUSES OF PREMATURE BATTERY FAILURES IN PV SYSTEM.
THE GROUP WILL CONSIST OF REPRESENTATIVES FROM THE PV PILOT PLANTS, BATTERY MANUFACTURERS, AND BATTERY RESEARCH INSTITUTES.
THE FIRST VERSION OF THE GUIDELINES FOR THE OPERATION AND MAINTENANCE OF BATTERIES HAS BEEN DISTRIBUTED TO PLANT MANAGERS AND ARE BEING IMPLEMENTED IN SOME PV SYSTEMS. THE SOC TESTING IS IN PROGRESS AND INITIAL RESULTS INDICATE THAT SOME UNITS ARE EASY TO USE AND EASY TO INSTALL. THE ACCURACY OF THE UNITS IS PRESENTLY BEING ASSESSED. A PROGRAMME HAS BEEN STARTED TO PERFORM BATTERY TESTS AT SOME OF THE PILOT PROJECTS. THESE TESTS WILL EXAMINE VARIATIONS BETWEEN CELLS IN A BATTERY AND IN SOME CASES CELLS WILL BE OPENED TO EXAMINE CAUSES OF PREMATURE CELL FAILURE. THE REMAINING WORK OF THE GROUP WILL INVOLVE:
- COOPERATING WITH THE CONCERTED ACTION ON COMPUTER MODELLING TO ASSESS VARIOUS BATTERY CONTROL STRATEGIES.
-COOPERATION WITH THE CONCERTED ACTION ON POWER CONDITIONING TO TEST VARIOUS CHARGE CONTROLLERS AND TO RECOMMEND IMPROVEMENTS.
FINALLY, A DETAILED REPORT ON THE CURRENT STATUS OF THE BATTERIES IN THE PV PILOT WILL BE COMPILED.
