Jamaica Energy Storage Charging Pile Project Bidding

How much reactive power does Bess supply?

BESS can supply nearly 10 MVAr of reactive power by consuming a small amount of energy. Fig. 11 plots the SOC of BESS#7 in different case studies. In most periods during the next day, due to the highest price uncertainty and the owner's risk aversion policy, case study 1 has the highest SOC.

How much power does Bess sell?

It is displayed in Fig. 14, at t = 4, BESS#15 sells 90 % of active power in the DAM and 10 % in the RTM; at t = 14, it sells 48 % of active power in the DAM and 52 % in the RTM, and at t = 22, it sells 62 % of active power in the DAM and 38 % in the RTM.

What is the most reliable bidding strategy for a Bess?

According to the analysis in Sect. 5.1, the most reliable bidding strategy for each BESS at this time is to declare its marginal cost curve as its supply function, so as to determine its own frequency regulation mileage quotation and capacity. Therefore, in this case, the five BESSs take their marginal costs as the declared supply function.

Does Bess have a state of charge (SOC)?

However, the participation of BESS in the electricity market is constrained by its own state of charge (SOC). Due to the inability to accurately predict the next day's real-time SOC, the mismatch between bidding strategy and real-time scheduling is easy to occur.

What does a 1C charge rate mean?

The C-rate defines the charging and discharging speed of a battery and is expressed as the ratio of current to the rated capacity (Ah). A 1C charging rate means the battery can be fully charged in one hour. The smaller the C value, the longer the charging time. A 1C discharge rate means the battery can be fully discharged in one hour.

What is a 1C battery?

A 1C battery is designed to charge or discharge at a rate equal to its full capacity within one hour. The “C” rating serves as a measure of how quickly the battery can deliver or accept energy. For example, a 2,000mAh 1C battery can safely discharge 2,000mA (2A) of current in one hour.

What is the difference between a 1C and 2C charge rate?

For example, a 1C rate means the battery will discharge completely in one hour. A 2C rate means the battery will discharge in half an hour, while a 0.5C rate will discharge in two hours. Similarly, for charging, a 1C rate would fully charge a battery in one hour, whereas a 0.5C rate would take two hours. Calculating the C-rate is straightforward.

What is the difference between 1C rate and 10AH battery?

For a battery with a capacity of 45Ah, a 1C rate equates to a discharge current of 45A; for a 10Ah battery, discharging at 1C rate means a discharge current of 10A. In both cases, the discharge time are the same, one hour. 1. Battery Capacity: The C-rate is closely related to battery capacity.

What is the charge and discharge rate of a battery?

Charge and discharge rates of a battery are governed by C-rates. The capacity of a battery is commonly rated at 1C, meaning that a fully charged battery rated at 1Ah should provide 1A for one hour. The same battery discharging at 0.5C should provide 500mA for two hours, and at 2C it delivers 2A for 30 minutes.

What happens if a battery reaches 1C?

Losses at fast discharges reduce the discharge time and these losses also affect charge times. A C-rate of 1C is also known as a one-hour discharge; 0.5C or C/2 is a two-hour discharge and 0.2C or C/5 is a 5-hour discharge. Some high-performance batteries can be charged and discharged above 1C with moderate stress.
