GbbOptimizer (a professional DESS alternative)

You can also try other DESS alternative: gbboptimizer.gbbsoft.pl

Program has two optimizers:

The first one try to discharge battery if during next 24h there will be too much power and/or charge battery if during next 24h you don't reach 100% (or other defined MaxSco). It can be joined with Dynamic Scheduler to move schedulers to cheapest prices or Dynamic Discharch to discharge on highest prices.
The second one is based on purchase prices, sale prices, value of energy in battery and maximizes profits (like Victron Dynamic ESS). But you have more control over it. For example, you can charge up to 90% but on selected days of month you can charge to 100% (this works also with first optimizer)

Program can also help you with:

Full statistic per hours, days and months.
change start of schedule(s) based on minimal purchase price for almost all countries in Europe.
discharge batteries based on maximal sale price.
force the sales of energy when the sale price is above the set price
limit the sales when the price is below zero.
optimize schedule(s) at night (or during cheap electricity tariff) in such way than on day there is a free place in battery for power from PV.
optimize 'Discharge Plan' in such way than on day there is free place in battery for power from PV.
delay charge battery to period with minimal prices in exchange for selling electricity
calculate profits (in money) from Victron and PV systems
InterPlant Balanser: for two or more noequal Plants connected to one grid optimizer tries to transfer excess energy from one plant to other (and not to grid)
'MasterPlant': to connect multiple Plants into one virtual Plant and optimize it as a whole. Good when you want to charge battery in ones plant from inverters in other plant (with Inter-Plant Balancer).
UK: 30 minutes time slots.
UK: different tariff for purchase and sales prices
UK: temporary change price for given period.

In additional:

Using ESS, so program respects all setting and limits.
Valuation of energy in the battery based on average purchase price (price only during charging from grid, charging from PV is free) and takes into account during optimalization
Optional include battery cost.
Import average house Load from VRM
Exclude extra loads (eg. EV car charging, heating pump) from house load profile
Import EV charger energy from Victron, from Tesla chargers, from HomeAssistant or automatically detect.
Forecast of Heating Pumps based on forecasted outside temperature.
Import PV forecast from one of 3 sources (including VRM itself)
Integration with HomeAssistant
Compare kWh from Victron with kWh from your Electricity Supplier

Technically:

This is SaaS = Software as a Service
Servers are located in EU
Victron: You don't install anything on Cerbo
Victron: You don't need NodeRed.
Victron: You must have connection with VRM.
Victron: The program connects to Cerbo once an hour and modifies Cerbo settings.

Yes, in "Gain/Profits" module. But now charge and discharge are calculated separately:

Efficiency also depends on BMS: how it really calculate SOC of battery. That why on my battery I have Discharge Efficency% >100% :-)

if your data are available by standard solcast API that no problem. If your data are available by other API than I must add new import.

No user has other than "hobbyist account" up to now. :-)

In Victron we have Schedulers = plan of charge, but there is no plan for discharge. So in GbbOptimizer there is plan for discharge:

Charge has higher priority then discharge.

2) Don't send power to grid until highest prices:

3) Discharge only during day or night (day=from sunrice to sunset)

@Peter can you please elaborate on how you capture data for EV, heatpump, etc.

For example, I have a non victron wallbox for my EVs and a separate tariff for heatpump and EVs (fixed price) from household (tibber).

With my local Node-Red installation, I am able to feed/provide Power-measurement for Grid, Household, heatpump and EVs, though...VRM is not able to distinguish these.

Also, I've read in your summary on your homepage, that PV-energy stored in battery (or directly used) is considered with a cost of zero, which is simply not true...at least for people which are allowed to feed-in for a fee, the are loosing that money, hence.

TIA,

Peter hominidae commented · Feb 18 at 07:53 PM

ad1. There are some methods to enter EV, heatpump etc data: (a) enter it manually (b) EV can be imported from VRM (c) if your EV charge has public API I can add import from this API. (d) if your tibber has API to import such information I can add import to program. For (c) and (d) contact with me on Discord.

ad2. I think you should start using program to understand way how program calculate gain/profit. Baseline is: how many you pay for energy for your loads without any PV, battery and feed-in. If optimalization causes than you pay less than this is your "Gain/profit". Optimizer try to increase your Profit. If you feed-in than this increase gain/profit. If you use PV energy for loads that this increase your gain/profit because you don't purchase power from grid.

You can use program without sending data to Cerbo (test mode)

> 2. DESS does not respect grid set point - eg. -200W in case of no import, no export

In our system you can setup GridSetpoint for every hour of day for export and default GridSetpoint when there is no export.

> In short, that means, in my mind I have a "Default target SOC" each day that I aim to achieve. As I have LFP chemistry in my battery, I aim to charge to 100% every day. [If I had NMC chemistry, in summer, I could aim to only charge to 80% if that is easily enough to get me through the night for battery longevity].

In GbbOptimizer there is option to try to get MaxSCO (parameter) every day. This can be 80% or 100% or other value you setup in plant properties. :-)
