Method and system using weighted generation capacity to improve management of electrical power generation facility

A method for managing an electrical energy generation facility comprising:

• an electrical energy generation device,
• an electrical energy storage device adapted for storing electrical energy generated by the electrical energy generation device and for outputting electrical energy to equipment connected to said facility,
• a control module configured for controlling the charging and discharging of the storage device,
• the method comprising the steps of:
• evaluating an electricity generation capacity of the generation device for a given period,
• determining a weighted generation capacity on the basis of said evaluated electricity generation capacity and at least one electricity generation capacity of said generating device evaluated over a period prior to said given period,
• determining, for a period subsequent to the given period, a discharge limit of the storage device on the basis of said weighted generation capacity, and
• during the subsequent period, limiting an amount of electricity output to the connected equipment on the basis of the discharge limit,
• wherein the weighted generation capacity for the given period is determined from the relation:
• Cp(t)=Σi=0kai(t)C(t−i)
• where Cp is the weighted generation capacity, t is the given period, t−i is a period prior to the given period, C(t−i) is the generation capacity during period t−i, k is a nonzero number of periods including period t for which the generation capacity of the generation device is taken into account when evaluating the weighted generation capacity for the given period, and ai(t) denotes a non-zero weighting factor for the generation capacity C(t−i) of period t−i, and
• wherein the weighted capacity is evaluated from the relation:
• Cp(t)=a(t)*C(t)+(1−a(t))*Cp(t−1),
• where a(t) is a factor between 0 and 1.
