Review flexibility_spec

[mabijkerk]

From flexibility_spec:

   describe "Electricity should be conserved" do

     it "between excess production and storage" do
      expect(@scenario.turk_excess_electricity_storage_sum.value).to be_within(0.000001).of(@scenario.turk_excess_electricity_from_production.value)
     end

   end

  end

Refers to the query turk_excess_electricity_storage_sum. This query seems to be outdated as it for example does not include flow batteries. The question is to which extent 'excess production' is still a relevant concept, given that all flexible technologies are now price-based. Critical review of flexibility_spec is therefore necessary.
