Project design > Grid-connected system definition > Grid systems

Implementing a storage in a PV system implies an specific cost of the stored energy, expressed as price/kWh. This cost corresponds indeed to the maximum energy stored in the battery pack

MAX CHARGING POWER TOO HIGH-HIGH VOLTAGE BATTERY

This is quite correct. For this Power limit you could even define a smaller battery pack, corresponding to one day of overload (see "clear day excess energy" on the next page). Now on the page "Peak shaving", you have to define the "Battery input charger" power which will charge the battery. Here you have probably defined a device of 50 kW

Battery system

We need to make simulation with battery system and set the system kind - storage strategy on self-consumption, and my question is, why is there no possibility to determine the time when to charge and discharge the batteries? For example i want to set the time for charging battery from 10 AM to 13 PM, and discharging time from 20 PM to 3 AM.

Battery aging

A battery is a chemical object, which may be subject to slow degradation along the time. In the database, we usually consider the degradation time as the warranty duration specified by the manufacturer. so that PVsyst doesn''t take this effect into account when studying the ageing of stand-alone systems. A model should be developed in the

Project design > Stand alone systems definition

Stand-alone systems are always organized around a battery storage: - a PV array charges the battery or directly delivers its power to the user. PVsyst doesn''t implement the inverter. The Load is specified as energy, whatever the way it will be used. Such systems may - rarely - be supported by a back-up generator in case of lack of energy.

Grid storage, system architecture

The DC bus is connected to the battery pack via a DC-DC converter. This mode requires a bi-directional DC-DC converter, for also ensuring the discharge of the battery to the DC bus. you can still evaluate its performance by defining suitable efficiencies in the PVsyst input and output storage parameters. You should simply check that the

Aging and Battery degredation

HiIf storage is defined within a project variant, does the aging tool calculate the loss for both the PV module and battery degradation, or just for the modules?If just for the modules, how can I include the effects of battery degradation?

Can I include a battery in a grid-connected system

Remember that the price of the stored energy is very high. It can be evaluated by the price of the battery pack, divided by the total energy stored along the battery lifetime, i.e. Capacity (in kWh) x DOD x Max. nb. of cycles. If you assume a full storage/destorage every day, a battery pack of 1''500 cycles should be replaced every 4 years.

Storage: Power''s peak shaving

-EBatCh - EBatDis: The battery storage efficiency loss (faradic efficiency, internal resistance, gassing), - CL_Chrg, CL_InvB: The charger and battery inverter''s efficiency losses,-EUnused: There may be some unused energy, either when the battery is full, or if the charging power overcomes the maximum power of the charger.

Battery model

PVsyst makes a distinction between the "static" longevity (named SOWStatic), i.e. when the battery is not in use (depending namely on the temperature), and the deterioration due to the use (charge/discharge cycles and depth of discharge), named SOWCycles. The battery life is usually admitted when the wear state attains 80% of the initial

5 FAQs about [Cuba pvsyst battery storage]

Can a grid-tied PV system have a battery storage?

More and more grid-tied PV systems are now equipped with a battery storage. The objective of such hybrid systems may be quite different from case to case. As examples: etc... Each of these uses of the PV energy will involve different sizings, constraints, energy flux, and quite different control strategies.

Does PVSyst treat the mode of charging a battery from the grid?

No, PVsyst doesn't treat the mode of charging the battery from the grid. This doesn't make much sense: what would be the strategy? When activating the charging ? Why? 1- This is the battery that I'm using the simulations. For this case, I'm only using one battery, so I should have a maximum capacity of around 200 kWh at 100% DOC.

How long does PVSyst take to charge a Li-ion battery?

Here you have defined a charging power of 100 kW, ensuring a charge in 1.6 hours under full sun. This is more reasonable. This is close to what is acceptable for Li-Ion batteries. This charging time was 10 minutes at sun in the previous case, and as PVsyst works in houly steps, this leads to some problems when simulating one full hour.

What sizing rules does PVSyst provide?

PVsyst will probably provide only rough sizing rules until some experience has been accumulated. Grid-storage systems require specific electronic devices, especially suited inverters, battery chargers, controllers, etc. Defining these devices in PVsyst will be extremely complex, as each manufacturer proposes its own integrated solution.

Can a 50 MW PV & energy storage system save CO2?

The results show that the 50 MW “PV + energy storage” system can achieve 24-h stable operation even when the sunshine changes significantly or the demand peaks, maintain the balance of power supply of the grid, and save a total of 1121310.388 tons of CO2 emissions during the life cycle of the system.
