Planning

Planning with the VEA is one of its strongest features.  Establishing a validated baseline is a computer model of the operating system over any desired period, whether it is a day or a year.  With variations of the baseline that resemble potential system changes that operate under the same conditions as the baseline will show the operational effects of a specific variation.  It is to the customer to decide what indicating parameters will be, with such as cost per period, emissions per periods, efficiencies per period, and other many possible measures.  Closer examination of the different parts of the system will often reveal truths that typically remain hidden.  The variations are typically less expensive; so many ideas may be exercised.  No parametric estimations, but realistic direct comparisons.  Decisions can be based on facts rather than estimations.

Case one: A university campus wished to operate its thermal system with more capacity at lower unit cost.  Several variations on the baseline showed how some variations proved highly beneficial while other variations that seemed to show promise did not simulate as well.

Case two: A district energy system wanted to know if any given PRV flow would operate a steam turbine generator to beneficially produce electrical power.  The VEA was able to pinpoint the best combination to suit as much of the PRV hourly flow over a year’s time as possible, and to compute the total electrical power to be produced with the revenue (as decreased electrical demand) this system would generate.
